[PATCH v3] imx8mp-evk: Add USB0 OTG support

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".

Changes since v2:
- Put the USB nodes in alphabetical order. (Marek)
- Remove unneeded pinctrl entry. (Marek)
