drm/i915/dp: Handle VSC SDP revision 7 in unpack

Browse source

VSC SDP revision 7 (Panel Replay + Pixel Encoding/Colorimetry Format)
unpacking is missing in intel_dp_vsc_sdp_unpack(). This causes pipe
state mismatches during state readout because the VSC SDP state is not
properly recovered when Panel Replay is active with colorimetry.

Add the missing case for revision 7 to intel_dp_vsc_sdp_unpack()
so that the state is correctly recovered.

v2: Rebase onto latest upstream
