[PATCH 39/51] drm/i915: Introduce intel_crtc_update_sarea_pos()

[ville.syrjala at linux.intel.com]

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

Refactor the code that stores the panning x/y position into the sarea.
Make the new function intel_crtc_update_sarea_pos() available to the
atomic mode setting code.
