media: atomisp: Add enum_framesizes function for sensors with selection / crop support

Browse source

Some sensor drivers with crop support (e.g. the ov5693 driver) only
return the current crop rectangle + 1/2 (binning) of the current crop
rectangle when calling their enum_frame_sizes op.

This causes 2 issues:
1. Atomisp sets to the crop area to include the padding, where as
   the enum_framesizes ioctl should return values without padding.

2. With cropping a lot more standard resolutions are possible then
   just these 2 and many apps limit the list given to the end user
   to the list returned by enum_framesizes.

Add an alternative enum_framesizes function for sensors which support
cropping to fix both issues.
