drm/amd/display: Don't allow FPO if no planes
In DCN32/321 FPO uses per-pipe P-State force. If there is no plane, then
then HUBP is power gated, in which case any programming in HUBP has no
effect and the pipe is always asserting P-State allow. This is contrary
to what we want to happen for FPO (FW should moderate the P-State
assertion), so block FPO if there's no plane for the FPO pipe.
