[PATCH 01/12] drm/i915: Move modeset_retry stuff into intel_connector.c

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

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

Most the modeset retry stuff look to be entirely generic, and
so there doesn't seem to any reason to keep it in intel_dp.c.
Move the generic bits into intel_connector.c.
