drm/i915/display: Allow fastsets when DP_SDP_VSC infoframe do not match
with PSR enabled
When PSR is enabled it handles DP_SDP_VSC, changing revision and all
the other fields as necessary.
It can also enabled and disable this SDP as needed without a full
modeset.
So here masking DP_SDP_VSC bit when previous and future state PSR
enabled, it will still be checked when comparing the asked state
to what was programmed to hardware.

This looks like a regression from the 5.13.0-20-generic kernel to the
5.15.0-17-generic kernel. The display works fine under efifb, but as
soon as the DRM drivers are loaded and KMS kicks in the display is
replaced by black with flickering white (apparently when what would be
on the output changes).
