drm/amd/display: WA for 3 display play video hot plug.
Three monitor connected and playing a video will
occupy all 4 pipes, if hot plug forth display,
commit streams will be failed due to no free pipe
can be found.
Work around:
When forth monitor connected, mark video plane as
a fake plane, remove it in dc, keep it in dm and
report address to OS, until OS turn off MPO.
