pixels and there are an additional 24 black rows "at the bottom".

The top-left coordinate is gotten from the registers specified in the
modes which are identical for both currently supported modes.

There are currently two modes supported by this driver: 2592*1944 and
1296*972. The second mode is obtained thanks to subsampling while
keeping the same field of view (FoV). No cropping involved, hence the
harcoded values.
