rockchip: handle peripheral as well as otg dr_mode

The OTG port is identified by inspecting the "dr_mode" property which is
expected to be "otg" for this port.  But it will work just as well as a
device controller when dr_mode is set to "peripheral", which may be
required if the mode detection pin is not set up correctly and the
device controller needs to be programmed to override this.
