[PATCH 07/14] drm/i915: Flag even inactive crtcs as "inherited"

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

I want to use the crtc_state->inherited flag to clean up some
of the early SAGV handling. To make that work nicely I need to
flag even the inactive crtcs as "inherited".

Since we can't expect user space to perform any real commits
on inactive crtcs we'll clear the flag already during
initial_commit().
