drm/i915: Move dsc/joiner enable into hsw_crtc_enable()
Lift the dsc/joiner enable up from the wonky places where it currently sits (ddi .pre_enable() or icl_ddi_bigjoiner_pre_enable()) into hsw_crtc_enable() where we write the other per-pipe stuff as well. Makes the transcoder vs. pipe split less confusing. For DSI this results in slight reordering between the dsc/joiner enable vs. transcoder timings setup, but I can't really think why that should cause any issues since the transcoder isn't yet enabled at that point. v2: Take care of dsi (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220125063937.7003-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
