Subject: usb: gadget: udc: renesas-usb3: clear VBOUT bit in DRD_CON

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

commit b2f1eaaee564c5593c303f4d15d827924cb6d20d upstream.

This driver should clear the bit. Otherwise, the VBUS will output
wrongly if the usb port on a board has VBUS output capability.

		      Renesas USB3.0 peripheral controller")
