[PATCH 2/5] drm: Swap w/h when converting the mode to src coordidates for a rotated primary plane

[ville.syrjala at linux.intel.com]

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

When converting the mode hdisplay/vdisplay to primary plane src
coordinates we need to take into account the current plane
rotation.
