Subject: [PATCH 6.1 120/451] arm64: dts: imx8mm-venice-gw71xx: fix USB OTG VBUS

From: Tim Harvey <tharvey@...eworks.com>

[ Upstream commit ec2cb52fcfef5d58574f2cfbc9a99ffc20ae5a9d ]

The GW71xx does not have a gpio controlled vbus regulator but it does
require some pinctrl. Remove the regulator and move the valid pinctrl
into the usbotg1 node.
