Handle only bigjoiner masters in skl_commit_modeset_enables/disables,
slave crtcs should be handled by master hooks. Same for encoders.
That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave.
v2: Get rid of master vs slave checks and separation in crtc enable/disable hooks.
Use unified iteration cycle for all of those, while enabling/disabling
transcoder only for those pipes where its needed(Ville Syrjälä)
v3: Move all the intel_encoder_* calls under transcoder code path(Ville Syrjälä)
