At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.
225 #include <linux/mod_devicetable.h>
This patch was build-tested on 20 different arch-es.
It also makes these drivers SubmitChecklist#1 compliant.

The v4l2-tpg*.h headers are meant to be used only internally by
vivid and vimc. There's no sense keeping them together with the
V4L2 kAPI headers. Also, one header includes the other as they're
meant to be used together. So, merge them.

Add support for the test_pattern control and the h/vflip controls.
This makes it possible to switch to more interesting test patterns and to
test control handling in v4l-subdevs.
There are more tpg-related controls that can be added, but this is a good
start.

These structures are all only stored in fields of v4l2_subdev_ops
structures, all of which are const, so these structures can be const
as well.

The vimc platform drivers define a platform device ID table but these
are not set to the .id_table field in the platform driver structure.
So the platform device ID table is only used to fill the aliases in
the module but are not used for matching (works because the platform
subsystem fallbacks to the driver's name if no .id_table is set).
But this also means that the platform device ID table isn't used if
the driver is built-in, which leads to the following build warning:
This causes the following build warnings when the driver is built-in:

Change the core structure for adding subdevices in the topology.
Instead of calling the specific create function for each subdevice,
inject a child platform_device with the driver's name.
Each type of node in the topology (sensor, capture, debayer, scaler)
will register a platform_driver with the corresponding name through the
component subsystem.
Implementing a new subdevice type doesn't require vimc-core to be altered.
This facilitates future implementation of dynamic entities, where
hotpluging an entity in the topology is just a matter of
registering/unregistering a platform_device in the system.
It also facilitates other implementations of different nodes without
touching the core code and remove the need of a header file for each
type of node.
