drm/amd/display: Add support for multiple overlay planes
[Why]
We only allowed 1 overlay plane. But now some ASICS can support multiple
overlay planes.
[How]
Use max_slave_planes as the number of overlays we can support.
Also since we cannot draw cursor over a video plane, we need to make
sure that we reject commits where the topmost plane is a video plane
(overlay only).
