Subject: [PATCH] drm/panel: Add and initialise an orientation field to
drm_panel from OF
"rotation" is listed as a standard property of panels in panel-common.yaml,
therefore it would be logical to process that from within the core
code should a panel driver not implement the get_orientation hook.
Call of_drm_get_panel_orientation from
drm_connector_set_orientation_from_panel to get that information.
This removes the need for any boiler-plate in panel drivers for calling
drm_connector_set_orientation_from_panel or
drm_connector_set_panel_orientation.
