drm/i915/display: Read PSR configuration before VSC SDP

Browse Source 
VSC SDP sending is taken care by PSR HW and it's not enabled in
VIDEO_DIP_CTL when PSR is enabled. Readback of VSC SDP is depending on
VSC_SDP being set in intel_crtc_state->infoframes.enabled. In case of PSR
setting this flag is taken care by PSR code -> read back PSR configuration
before reading VSC SDP otherwise we get pipeconfig mismatch error.
