[PATCH v2 5/7] drm/i915/display: Ignore only psr specific part of vsc sdp

[Jouni Högander]

Pipe config check is currently ignoring vsc sdp changes completely
if psr is enabled. We want to ignore only PSR part of it as there
might be changes in colorimetry data. Also read back vsc_sdp when psr is
used.
