[Intel-gfx] [PATCH 02/10] drm/i915: Fix bigjoiner state copy fails

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We seem to be missing a few things from the bigjoiner state copy.
Namely hw.mode isn't getting copied (which probably causes PIPESRC
to be misconfigured), CTM/LUTs aren't getting copied (which could
cause the pipe to produced incorrect output), and we also forgot
to copy over the color_mgmt_changed flag so potentially we fail
to do the actual CTM/LUT programming (assuming we aren't doing
a full modeset or fastset). Fix it all.
