description:
Various improvements from t-hash (very very slightly tweaked by me)
+ Use usbd_xfer_isread().
+ Change mutex to be initialized at IPL_USB.
+ Add vendor init/portsc hook.
+ Modify xhci_trb_put() to take host byte order arguments and
convert them to little endian byte order.
+ Return PCI vendor ID of xhci instead of NetBSD(0x0) as a root hub
vendor ID like other HCs do.
+ Move sc_ih in struct xhci_softc to struct xhci_pci_softc.
+ Improve debug message.
