Intel Display KP at boot after Whatevergreen+Lilu upgrade #18

I'm in the process of upgrading things in prep for an OS upgrade. With the current config, upgrading Whatevergreen results in a kernel panic on boot.

I managed to narrow this down tonight: if you remove enable-dpcd-max-link-rate-fix from the PciRoot(0x0)/Pci(0x2,0x0) portion of OC config, it's possible to upgrade Whatevergreen and Lilu. As best I can tell, things still work as expected. The internal display is still outputting at full retina res, and sleep works for me too.

Figured you'd want to know if you're heading toward an upgrade too!
