"Third set of IIO new drivers, cleanups and fixes for the 3.9 cycle

New drivers
1) A driver for ST microelectronics sensors.  This driver already covers
   a large set of new parts (20 gyros, accelerometer and magnetometers)
   not currently covered by the existing drivers.  The intent moving forward
   is to merge this with the other drivers for similar parts already in tree.
   The lis3l02dq driver currently in staging/iio will be trivial, the lis3
   driver in misc more complex as it has a number of additional interfaces.
   Any merging in of the lis3 driver will rely on the not currently
   merged iio_input bridge driver and handling of freefall notifications
   etc.

2) A driver for the itg3200 gyroscope.

Graduations from staging
1) Cleanup and move out of staging of the adxrs450 gyroscope driver.  The
   cleanup required was all minor but there were a couple of fixes hidden in
   there.

Core and driver additions
1) Initial work from Guenter Roeck on device tree support for IIO's provider/
   consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver.
   The full device tree syntax is currently under discussion but should
   follow shortly.

Cleanups and fixes
1) Remove a noop function __iio_update_buffer
2) Couple of small fixes and cleanups for the max1363
