drm/amd/display: Set color_mgmt_changed to true on unsuspend

misyltoad · alexdeucher · commit 6e7a41762479 · 2024-04-18T23:47:07.000-04:00
Otherwise we can end up with a frame on unsuspend where color management
is not applied when userspace has not committed themselves.

Fixes re-applying color management on Steam Deck/Gamescope on S3 resume.
