The MDP4/5 DT node now contains a list of ports that describe how it
connects to external encoder interfaces like DSI and HDMI. These follow
the standard of_graph bindings, and allow us to get rid of the 'connectors'
phandle that contained a list of all the external encoders connected to
MDP.
The GPU phandle is removed too until we figure out what's the right way
to specify it in DT.
