drm/i915: Constify the state arguments to the color management stuff
Pass the crtc state etc. as const to the color management commit functions. And while at it polish some of the local variables. v2: Rebase Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190205160848.24662-4-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
