drm/amdgpu: Implement "color format" DRM property

Browse source

The "color format" DRM property allows userspace to explicitly pick a
color format to use. If an unsupported color format is requested,
userspace will be given an error instead of silently having its request
disobeyed.

The default case, which is AUTO, picks YCbCr 4:2:0 if it's a 4:2:0-only
mode, and RGB in all other cases.
