some renesas_usbhs device is supporting OTG external device interface. In that device, it is necessary to control PWEN/EXTLP on DVSTCTR. This patch support it. But renesas_usbhs driver doesn't have OTG support for now. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
