drm/amd/display: Enable FPO for configs that could reduce vlevel
[Description]
- On high refresh rate DRR displays that support VBLANK naturally,
UCLK could be idling at DPM1 instead of DPM0 since it doesn't use
FPO
- To achieve DPM0, enable FPO on these configs even though it can
support P-State without FPO
- Default disable for now, have debug option to enable
