On some hardware the LCD panel is not mounted upright in the casing, but rotated by 90 degrees. In this case we want the console to automatically be rotated to compensate. The drm subsys has a quirk table for this, use the drm_get_panel_orientation_quirk function to get the panel orientation and set info->fbcon_rotate_hint based on this, so that the fbcon console on top of efifb gets automatically rotated to compensate for the panel orientation.
