grub xhci support 

see:

https://github.com/9elements/grub/commits/xhci-module-upstreaming-squash_v4/

grub only supports xhci on bios/uefi targets, but not coreboot.
some newer machines don't have ps/2 controllers, and boot in a
way where ehci isn't available at startup; the controller can't
be used by ehci code, there must be xhci support.

the code is from Patrick Rudolph working on behalf of 9elements.
the code was also sent here for review:

https://lists.gnu.org/archive/html/grub-devel/2020-12/msg00111.html

however, upstream never merged these patches. libreboot will have
to maintain these from now on. the patches have been rebased for
use with grub 2.12.

From 90c9011f2e0350a97e3df44b0fc6dd022e04c276 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/8] grub-core/bus/usb: Parse SuperSpeed companion descriptors
Parse the SS_ENDPOINT_COMPANION descriptor, which is only present on USB 3.0
capable devices and xHCI controllers. Make the descendp an array of pointers
to the endpoint descriptor as it's no longer an continous array.

Subject: [PATCH 7/8] grub-core/bus/usb/usbhub: Add xHCI non root hub support
Tested on Intel PCH C246, the USB3 hub can be configured by grub.
Issues:
* USB3 devices connected behind that hub are sometimes not detected.
