Update to Linux 6.1.4 and latest uboot, upgrade to nixos-22.11

Hi, I've been fumbling around i the dark for a good long while trying to find a way to build this with a newer kernel and against nixos-22.11.

For a long while I could not get the screen working with the new kernel, but I've finally landed on something workable, and now the screen initializes in time to show the luks prompt, so no more typing the password blindly. :smiley:

I ended up updating uboot as well, and that fixed the screen in the initial boot stages! This means I'm finally able to roll back to a previous generation without bringing out the screwdriver and recovery sdcard. :partying_face:

Two things I did along the way that I'm particularly unsure about:

• Moved adding dtbs to the postPatch phase to allow building in 22.11
• Removed the large custom kernel-config (it caused a lot of build errors with 6.x kernels and I didn't see a reason to keep it)

Resolves #8

FWIW, I've forked this project, merged in your changes, and built on them: https://codeberg.org/lykso/hardware-mnt-reform

Great job getting the screen working during the early boot. I'd have probably given up without your contributions here.

@lykso, that is fantastic! I've switched to your fork and am running 6.1.62. If I get around to fixing more stuff I'll send my PRs your way next time :smiley:
