AFBC has a mode that guarantees use of AFBC with an uncompressed
payloads, we add a new modifier to support this mode.
V2: updated modifier comment

Add new properties to specify x,y coordinates and
width and height for writeback.
These are reset to 0 on duplicating state to provide
robustness against accidental scaling.

The phase setting part of malidp_crtc_atomic_check_scaling is refactored
to allow use in writeback scaling.
Also the enable_memwrite function prototype is simplified by directly
passing mw_state.

Add support for scaling on writeback. To do this add writeback_w and
writeback_h as writeback connector properties to specify the desired
output dimensions.
Then implement downscaling on writeback for Malidp-550 and Malidp-650
(upscaling on writeback is not supported on these devices).
