For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.
Also had to refactor intel_can_enable_sagv function,
as current seems to be outdated and using skl specific
workarounds, also not following BSpec for Gen11+.
v25: Rebased patch series as part was merged already
v26: Had to resend the whole series as one more mid patch was added
v27: Patches 2,3,7 were pushed, have to resend the series to prevent
build failure.
v28: PCode patch was merged, one patch was added, sent new series.
v30: 3 patches merged, resending the rest with comments fixed
