From: Fabio Estevam festevam@denx.de
Add USB0 OTG support.
Currently, the USB0 OTG nodes are not enabled in the Linux kernel devicetree.
For this reason, enable the USB0 OTG nodes inside imx8mp-evk-u-boot.dtsi for now.
Also select several useful options such as USB gadget and fastboot.
Tested by running "ums 0 mmc 2".
