drm/amd/display: Disable cursors before disabling planes

Browse source

[Why]
We can't do cursor programming after the planes have been disabled
since there won't be any pipes - leading to lock warnings and the wrong
cursor state being left in the registers.

When we re-enable the planes after the previous cursor state will also
remain if we don't have a cursor plane.

[How]
If we're disabling the planes then do the cursor programming first.
If we're not disabling the planes then do the cursor programming after.

Introduce the amdgpu_dm_commit_cursors helper to avoid code duplication
for both of these cases.
