drm/radeon/kms: add support for router objects
router objects are found on systems that use a mux to control ddc line to connector routing or to control the actual clock and data routing from the chip to the connectors. This patch implements ddc line routing. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
