lp/drivers/usb: Add quirk for QEMU XHCI root hub
The QEMU XHCI driver does not implement the Port Change Detect bit
in the USBSTS register. As a result no devices are attached without
looking at each port individually.
Detect this as a quirk based on the QEMU XHCI controller PCI ID,
and apply it to the root hub quirk list so it can get used by the
generic hub driver to skip this check.
With this change an attached USB mass storage device is detected and
able to boot when supplied to qemu:
-drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img
-device qemu-xhci,id-xhci
-device usb-storage,bus=xhci.0,drive=usbmsc
