drm/i915: Simplify hdmi_12bpc_possible()
With the output_types bitmask there's no need to loop through the encoders anymore when checking for HDMI+non-HDMI cloning. v2: Use output_types bitmask v3: Fix the logic to really check that there are no non-HDMI encoders Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> (v2) Link: http://patchwork.freedesktop.org/patch/msgid/1466621833-5054-11-git-send-email-ville.syrjala@linux.intel.com
