Comment (by kallisti5):
It feels like the XHCI bus driver is mapping the wrong memory location.
Everything it reads is 0xffffffff (including XHCI_HCI_CAPLENGTH)
I see mentions of using BAR0 and BAR1 on 64-bit platforms for the register
locations in the XHCI spec... but I don't see code for that in our XHCI
driver :-|
