hell yeah, got displayport alt mode over usb-c working on rk3588 pocket reform with mainboard 2.0!

in the end it was a DP lane polarity issue: USB3 allows lane polarity swap for better PCB routing, but DP doesn't. tricky when you need to reuse the same lanes for both.

but wait... does that mean MNT Pocket Reform can have 3 displays now (1 DP, 1 HDMI, 1 internal)? yes, yes it can!
