[PATCH 1/2] drm: Set crtc->invert_dimensions from the atomic helpers

[ville.syrjala at linux.intel.com]

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

Pull the crtc->invert_dimensions setting from omapdrm into the atomic
helpers so that all drivers will check viewport correctly in setcrtc()
after rotating the primary plane,
