Setting DP_PSR_SU_REGION_SCANLINE_CAPTURE (Selective Update Region Scan
Line Capture Indication in spec) bit was dropped when psr_enable_sink was
split to _psr_enable_sink and _panel_replay_enable_sink. Add setting it
back.
Fixes: 32f0045f905c ("drm/i915/psr: Split enabling sink for PSR and Panel Replay")
