First two patches are cleanup patches with no functional changes to
rename the existing update_crtc() hook to commit_modeset_enables() to better
match the drm_atomic naming conventions.
This also prepares to add new hook for ICL since that adds support for
transcoder port sync feature.
Rest of the patches enable transcoder port sync feature starting GEN 11
required to synchronize the two tile sent across two DP SST connectors.
This has been validated using IGT to enable Dell tiled monitor in a 2 pipe
2 port configuration.
