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.

@mntmn This is awesome! I remember many people having asked for this QoL feature during the last year. Congratulations that you got this working! 🎉

@mntmn I am *very* tempted to make my next monitor a display-port monitor given these news. :)
