Improve the table containing hardware information related to the
supported plane formats:
1. Move (part of) the overlay format register settings from multiple
switch() statements spread across the code into the table, like is
already done for the primary plane register settings,
2. Remove the .yuv field, as that information can easily be extracted
from the register settings using a new helper macro,
3. Shrink and move the .bpp field to reduce table size.
