The move of format translation initialisation into soc_camera_open() was
temporary for the soc-camera as platform driver intermediate step, put it back
into soc_camera_probe(). Also add a .put_formats() method to
soc_camera_host_ops to free any resources host driver might have allocated in
.get_formats().

V4L2 drivers are allowed to configure a geometry different than what has been
requested by the user with S_CROP, but then they have to adjust the input
rectangle accordingly. Fix ov772x to comply with this requirement.

1. soc-camera always requests a valid rectangle, when calling .s_fmt(), no need
to check and adjust
2. in .s_crop(), if the rectangle exceeds sensor limits, push it to the
respective border instead of centering
3. take into account left and top borders when checking

Convert the soc-camera framework to use the v4l2-(sub)dev API. Start using
v4l2-subdev operations. Only a part of the interface between the
soc_camera core, soc_camera host drivers on one side and soc_camera device
drivers on the other side is replaced so far. The rest of the interface
will be replaced in incremental steps, and will require extensions and,
possibly, modifications to the v4l2-subdev code.

Convert soc-camera core and all drivers to platform device API. We already

now we remove the compatibility code and switch completely to the new scheme.

This the vpfe capture bridge driver for doing video
capture on DM355 and DM6446 evms. The ccdc hw modules register with the
driver and are used for configuring the CCD Controller for a specific
decoder interface. The driver also registers the sub devices required
for a specific evm. More than one sub devices can be registered.
This allows driver to switch dynamically to capture video from
any sub device that is registered. Currently only one sub device
(tvp5146) is supported. But in future this driver is expected
to do capture from sensor devices such as Micron's MT9T001, MT9T031
and MT9P031 etc. The driver currently supports MMAP based IO.
