[PATCH v2 3/4] usb: support 64-bit pci bars

[Nikunj A Dadhania]

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.
