  r344633:
  usb_nop_xceiv: Add support for this pseudo device
  
  This is a "fake" phy that handle regulator, clocks and reset gpio.
  Only clock and regulator is supported for now.

  r344634:
  xhci_mv: Move the driver to generic_xhci
  
  Marvell XHCI is in fact generic-xhci, so move the driver and
  add the compatible string.
  While here, get and enable the phy if the dtb provide one.
  The xhci bindings state that phys should be in a 'phys' property but
  Marvell DTS uses 'usb-phy', only add support for 'usb-phy' for now.
