GRUB: remove XHCI patches for now (will re-add)

Fixes this bug:
https://codeberg.org/libreboot/lbmk/issues/216

Well, fix is the wrong word. We want xHCI ideally.

Mate is working on it as I write this. I've also:

* Disabled CONFIG_FINALIZE_USB_ROUTE_XHCI on Haswell
  boards (coreboot)
* Disabled the GRUB payload on HP 820 G2 for now

We will need to re-add the xHCI patches once fixed.
If Mate/we can't fix it, I'll contact Patrick
Rudolph who originally wrote the xHCI patches.
