Apparently xhci(4) also needs a hook to set the address of a device.
Some Low/Full speed devices do not like to get a SET_ADDRESS command
before we have read (some bits of) their device descriptor. So change
the attach logic to issue two "Device Address" command with a BSR dance.
This should fix the "device problem, disabling port" error seen on root
hubs with some Low/Full speed devices, reported by miod@.
