drm/amd/display: treat plane clip size change as MED update type
[why]
When clip size is changed recout and viewport size would require an
update. When the update is clip size only current driver fails to
program the update into hardware.
[how]
Set a new clip_size_change flag when it is detected and set MED update
type and reprogram scaling params in next program pipe.
