grub/xhci: Add xHCI non-root-hub fixes from Nitrokey

Browse Source 
See:
https://github.com/Nitrokey/nethsm-grub/commits/nethsm-z790?since=2025-01-13&until=2025-01-13

And more generally, see branch:
https://github.com/Nitrokey/nethsm-grub/commits/nethsm-z790

This brings in a few minor fixes, and also a not-so-minor fix:
Add TT (transaction translation) handling for non-SuperSpeed
devices in xhci.c

More generally, this patchset will improve non-root hub support
in the xHCI code. There is also a patch to work around a quirk
on the MSI Z790-P mainboard, which I'm planning to add to Libreboot
at a later date.
