Subject: drm/amd/display: skip phantom pipes when checking for pending flip
Git-commit: c08978577a7b17736d9680aaa7e0d22dc775c326
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[Why&How]
Phantom pipes are not programmed fully to hardware and hence we should
not expect a flip completion.
