drm/amd/display: Turn on phantom OTG before disabling phantom pipe
[Description]
- Proper phantom pipe disable sequence was missing in
commit_planes_for_stream
- If disabling phantom pipe, turn on phantom OTG first, and turn
off the phantom OTG after the plane is disabled
- Also update sequence for enabling / disabling phantom streams
(apply_ctx_to_hw). When enabling phantom pipes, enable before
doing front end programming for phantom pipes. If disabling
phantom pipes, disable after front end programming (i.e. after
phantom plane disable)
- TODO: Still need to properly handle transition case when a phantom
pipe is transitioned directly into a real pipe (need to fully disable
the phantom pipe first)
