media: mexon-ge2d: fixup frames size in registers

Browse source

The CLIP, SRC & DST registers are coded to take the pixel/line start & end,
starting from 0. Thus the end should be the width/height minus 1.

It can be an issue with clipping and rotation, where it will add spurious
lines from uninitialized or unwanted data with a shift in the result.
