From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
[ Upstream commit 09938ea9d136243e8d1fed6d4d7a257764f28f6d ]
This patch fixes and issue that the vbus_ctrl is disabled by rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot supply the vbus.
Note that this condition will exit when the otg irq happens even if we don't apply this patch.
