Subject: [PATCH 07/10] ARM: dts: imx6ul-kontron-n6x1x-s: Add vbus-supply and
 overcurrent polarity to usb nodes

From: Frieder Schrempf <frieder.schrempf@...tron.de>

To silence the warnings shown by the driver at boot time, we add a
fixed regulator for the 5V supply of usbotg2 and specify the polarity
of the overcurrent signal for usbotg1.
