xhci: Update the times for usb command timeouts.
The xhci controller had a hardcoded 1 second timeout for both bulk and
control transfers. The 1 second bulk timeout is too small for some
real devices.
Increase both times to 5.1 seconds - according to the USB spec, the
maximum time a command should take is 5 seconds. However, have the
set_address command only wait for 150ms (spec says set_address should
take no more than 50ms).
Introduce usb_xfer_time() to calculate maximum command time.
