drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x
There have recently been changes that break backwards compatibility, that were introduced into DMUB firmware (for DCN32x) concerning FPO and SubVP. So, since those are just power optimization features, we can just disable them unless the user is using a new enough version of DMUB firmware.
