Just FYI I also got the internal display to work after some fixes to
the dtsi [1] and copying the stuff over from the ChromeOS kernel tree.

It might be harder to enable the external display, given that we don't
have a good way of describing the weird design of using the DP bridge
also as a mux. See [2] for ongoing discussion.
