- get rid of ridden V4L2_COMMON symbol
This symbol is not needed anymore; it can be folded with V4L2
one, simplifying the Kconfig a little bit;
- Comment why some Kconfig items are needed;
- Remove if test for MEDIA_CAMERA_SUPPORT, replacing it by
depends on.

Driver for mt9v022 camera sensor is fully compatible for mt9v024 camera sensor
with the exception of several registers which have been changed addresses.
mt9v024 also has improved and additional features, but they are currently not in use.

The sensor starts streaming video as soon as it gets powered or is
reset. Disable the output in the reset function.

Conversion from i2c_client to ov772x_priv is only needed in a single
location, while conversion from v4l2_subdev to ov772x_priv is needed in
several locations. Perform the former manually, and use to_ov772x for
the later.

The format and window size are only initialized during the first g_fmt
call. This leaves the device in an inconsistent state after
initialization, which will cause problems when implementing pad
operations. Move the format and window size initialization to probe
time.

Several client drivers access the hardware at probe time, for instance
to read the probe chip ID. Such chips need to be powered up when being
probed.
soc-camera handles this by powering chips up in the soc-camera probe
implementation. However, this will break with non soc-camera hosts that
don't perform the same operations.
Fix the problem by pushing the power up/down from the soc-camera core
down to individual drivers on a needs basis.

Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.

It makes sense to latter break it into a few other dirs.
