drm/simpledrm: Add "panel orientation" property on non-upright mounted LCD panels

commit 94fa115f7b28a3f02611499175e134f0a823b686 upstream.

Some devices use e.g. a portrait panel in a standard laptop casing made
for landscape panels. efifb calls drm_get_panel_orientation_quirk() and
sets fb_info.fbcon_rotate_hint to make fbcon rotate the console so that
it shows up-right instead of on its side.

When switching to simpledrm the fbcon renders on its side. Call the
drm_connector_set_panel_orientation_with_quirk() helper to add
a "panel orientation" property on devices listed in the quirk table,
to make the fbcon (and aware userspace apps) rotate the image to
display properly.
