dev/usb2: use @1 for root hub port index
A hub is an USB device and devices' "port numbers range from 1 to 255"
according to Open Firmware, Recommended Practice: Universal Serial Bus (Version
1, June 1, 1998).
Linux thinks the same and if we kept indexing from zero it wouldn't
associate the Device Tree firmware node with the device instance.
Before:
USB devices:
/usb@d4208000/hub@0,0
/usb@d4208000/hub@0,0/scsi@4,0
/usb@d4208000/hub@0,0/ethernet@3,0
/usb@d4208000/hub@0,0/scsi@4,0/disk
After:
USB devices:
/usb@d4208000/hub@1,0
/usb@d4208000/hub@1,0/scsi@4,0
/usb@d4208000/hub@1,0/ethernet@3,0
/usb@d4208000/hub@1,0/scsi@4,0/disk
