[PATCH 18/29] drm/amd/display: Don't check output BPP for phantom

[Tom Chung]

From: Alvin Lee <alvin.l...@amd.com>

[Description]
- If we're enabling phantom pipe for a high
  link rate display we could
  fail DML on the phantom pipe since it's
  set to virtual signal
- Therefore don't consider Output BPP for
  phantom pipe
