Log message:
Save and restore the (non-standard) USBMODE register around a reset of the
controller. This register controls whether the controller is in device or
host mode on many dual role controllers and gets reset during a reset of
the controller, placing the controller in (non-functional) idle mode. By
saving and restoring it, we keep the controller in host mode. Since this is
a non-standard register, add a new EHCIF_USBMODE flag and only do the save and
restore if it has been set.
Makes the upper "OTG" port of the Cubox-i work.
