drm/amd/display: Reject non-zero src_y and src_x for video planes
[Why]
This hasn't been well tested and leads to complete system hangs on DCN1
based systems, possibly others.
The system hang can be reproduced by gesturing the video on the YouTube
Android app on ChromeOS into full screen.
[How]
Reject atomic commits with non-zero drm_plane_state.src_x or src_y values.
v2:
- Add code comment describing the reason we're rejecting non-zero
src_x and src_y
- Drop gerrit Change-Id
- Add stable CC
- Based on amd-staging-drm-next
v3: removed trailing whitespace
