The DisplayPort found on RK3576 is very similar to that of RK3588,
but work in dual pixel mode and support for MST.
This patch series aims to add basic display output, not include audio
and MST, which will be the work for the next stage.
Tested with 2 lane standard DP port and USB-C Alt mode output now.
For those who want to give it a try, I have a reference branch here[0].

integration stage
