Extracted from my system configs. There's still a few issues with this
machine:
1. Audio is a lost cause. Will probably need to bribe an Apple or Cirrus
engineer for the datasheet.
2. The thunderbolt module will oops upon system resume, and subsequently
refuse to work until next reboot.
3. The d3cold state needs to be disabled on the NVME controller for it
to wake up.
4. The Bluetooth UART (/dev/ttyS0) is created and then deleted by udev
in early boot. I am yet to figure out why. Hack around it by
reloading the 8250_dw module, causing it to be re-created.
