This set of patches enables transcoder port sync to synchronize tiled displays
across multiple SST DP ports using the master-slave model.
This has been tested with kms_dp_tiled_display.c IGT test which validates
the page flip synchronization.
This set of patches addresses the final set of comments from Ville
and Maarten.

across separate ports
drm/i915/display/icl: HW state readout for transcoder port sync config
drm/i915/display/icl: Enable master-slaves in trans port sync
drm/i915/display/icl: Disable transcoder port sync as part of
crtc_disable() sequence
drm/i915/display/icl: In port sync mode disable slaves first then
