drm/radeon/kms: add support for clock/data path routers
This is a follow on to:
26b5bc986423cf3887e09188cb662ed651c5374d
(drm/radeon/kms: add support for router objects)
That patch added support for systems that use a mux to control
the ddc line routing between the connectors. This patch adds
support for systems that use a mux to control the encoder
clock and data path routing to the connectors.
Should fix:
