For board-qemu, USB scan had to be triggered manually so far. Now it is run
automatically during each boot when an OHCI controller is available.
To determine the base address of the OHCI controller, we need translate-address.
However, this function does not work during the PCI scan on real hardware yet,
since the "assigned-addresses" properties might not be set up yet. Therefor the
translate-address is now done in the file usb-ohci.fs, which is now included
during the USB scan instead of the PCI scan.
For the real JS2x hardware there were also some words missing, like dma-alloc.
These are now provided, too, so the USB code now works on both again, emulated
and real hardware.
