drm/i915: Introduce i9xx_has_pfit()
Make the code self-documenting by introducing i9xx_has_pfit(). Also make PNV an exceptional case so that we can unset .is_mobile for the desktop variant. v2: s/gen4/gen>=4/ (Tvrtko) Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190319142329.22881-1-ville.syrjala@linux.intel.com Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
