Subject: drm/amd/display: Enable 3-plane MPO for DCN31
Git-commit: e9ebc23b3fb2949e18c6df98a6e6fd94429e498e
Patch-mainline: v5.19-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
[WHY&HOW]
It can be enabled by users, but proper way is to report max_slave_planes
in DC caps for each ASIC.
Some structures use hardcoded max_plane=2, this is also addressed here.
