[PATCH v3 05/15] drm/atmel-hlcdc: Use per-plane rotation property

[ville.syrjala at linux.intel.com]

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

The global mode_config.rotation_property is going away, switch over to
per-plane rotation_property.

v2: Propagate error upwards (Boris)
v3: Drop the BIT()
