USB1 is connected to the on-module USB 3.0 hub and power to the hub
should be controlled via setting/clearing the FEAT_POWER flag in the
root hub.
This adds a 'xhci,port-power' stringlist to enable the infrastructure
in xhci.c to find and control the fixed regulator associated with
control of the USB hub.
