usb: support 64-bit pci bars
With the addition of 64-bit bar ranges (commit: 9fbfed08 - pci: use
64bit bar ranges), the usb-setup-hcidev needs to handle 64-bit
addresses.
For example, QEMU provided NEC USB XHCI device requests 64-bit memory
address. Added code to check the memory type before address
translation.
