For each type of compass supported (AK8975 and AK8963),
add a definition structure for register masks, important registers,
raw data interpretation.
This change will make integrating new type of devices easier.

* two state transition events (running and walking)
* a new channel IIO_STEPS and support for reading and writing
pedometer step counter
* step detect event
* a new IIO_CHAN_INFO_CALIBHEIGHT mask bit for reading and writing

Some devices need the height of the user to compute various
parameters. One of this devices is Freescale's MMA9553L
(http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf)
that needs the height of the user to compute the stride length which
is used further to determine distance, speed and activity type.

These changes are needed to support the functionality of a pedometer.
A pedometer has two basic functionalities: step counter and step detector.
The step counter needs to be enabled and then it will count the steps
in its hardware register. Whenever the application needs to check
the step count, it will read the step counter register. To support the
step counter a new channel type STEPS is added. Since the pedometer needs
to be enabled first so that the hardware can count and store the steps,
we need a specific ENABLE channel info mask.
The step detector will generate an interrupt each time a step is detected.
To support this functionality we add a new event type INSTANCE.
For more information on the Android requirements for step counter and step
detector see:
http://source.android.com/devices/sensors/composite_sensors.html#counter
and http://source.android.com/devices/sensors/composite_sensors.html#detector.
A device that has the pedometer functionality this interface needs to
support is Freescale's MMA9553L:

This channel will be used for exposing information about
activity composite sensors. Activities supported so far:
* running
* jogging
* walking
* still
THRESHOLD event is used to signal a change in the activity
state.
We associate a confidence interval for each activity expressed
as a percentage from 0 to 100.
* 0, means the sensor IS NOT reporting that activity.
* 100, means the sensor IS reporting that activity.
Users of this interface have two possible means to gather
information about the ongoing activities.
1. Event based, via event file descriptor
* sensor may report an event when ENTERING an activity or LEAVING
an activity based on a threshold value.
* drivers will wake up applications waiting data on the event fd
2. Polling, by reading the sysfs associated attribute files:
* /sys/bus/iio/devices/iio:device0/in_activity_running_input
expressed as percentage confidence value from 0 to 100.
This will offer an interface for Android significant motion
composite sensor defined here:
http://source.android.com/devices/sensors/composite_sensors.html
Activities listed above are supported by Freescale's MMA9553 sensor:

We need a way to store events generated by iio_dummy_evgen module,
in order to correctly process IRQs in iio_simple_dummy_events.
For the moment, we add two registers:
* id_reg - ID register, stores the source of the event
* id_data - DATA register, stores the type of the event
e.g echo 4 > /sys/bus/iio/devices/iio_evgen/poke2
id_reg 0x02, id_data 0x04
This means, event of type 4 was generated by fake device 2.
We currently use a hardcoded mapping of virtual events to IIO events.

The Onda v975w tablet contains an accelerometer that's advertised over
ACPI as SMO8500. This device is however a KXCJ9 accelerometer as
can be seen in the Windows driver's INF file, and from the etching on
the chipset ("KXCJ9 41566 0414").
This patch also removes the attempt to get the IRQ for the "data ready"
signal, as it does not seem to be supported by this device on this
platform.

Now that Comedi has the structures in place to support setting the
current "read" and/or "write" subdevice on a per-file object basis, add
new ioctls to set them. The newly chosen "read" ("write") subdevice
needs to support "read" ("write") commands, and the file cannot be busy
handling a "read" ("write") command on the previous subdevice (if any).

Comedi devices may have several subdevices that support "read" and/or
"write" asynchronous commands that use the "read" or "write" file
operations for data transfer. The low-level Comedi drivers may nominate
a default "read" subdevice and/or a default "write" subdevice, but it
may have other subdevices that support asynchronous commands.
The Comedi core provides a somewhat clunky mechanism to provide access
to the asynchronous command support of the non-default subdevices. When
a low-level device is "attached" to a core Comedi device, it dynamically
allocates a minor device number for each of the subdevices that support
asynchrounous commands and associates them with files created in SysFS
named "comediX_subdY", where "X" is the minor device number of the main
comedi device, and "Y" is the subdevice number. An application can open
these subdevice-specific files and they behave like the regular
"comediX" files except that the "read" and/or "write" subdevice may be
different to the default chosen by the low-level driver.
This patch adds a layer of indirection between the file object and the
comedi device object to allow the current "read" and/or "write"
subdevice to be altered after opening the Comedi device, on a per-file
object basis. The advantage is that an application only needs to open
the main Comedi device file and can then choose which subdevice it wants
to "read" or "write". The main Comedi device file can be opened more
than once, and each file object can choose the "read" and "write"
subdevices independently.
The new `struct comedi_file` is created on "open" and freed on
"release". It includes pointers to the main Comedi device structure,
and to the current "read" and "write" subdevice structures (which may be
NULL). It also has information to keep track of when a low-level device
has been attached or detached since the previous time the file object
was used. In that case, the current "read" and "write" subdevices in
the `struct comedi_file` will be changed to the new defaults (or set to
NULL). (The change to new defaults is done by `comedi_file_reset()`.
The checking for attach/detach is done by `comedi_file_check()` which
will call `comedi_file_reset()` if there have been any attach/detach
operations since the previous call.)
A subsequent patch will add the ioctls to change the current "read" and
"write" subdevices.
