ARM: tegra: enable USB device mode and UMS on some boards
For each of Jetson TK1, Venice2, and Beaver:
- Enable the first USB controller in DT, and describe its configuration.
- Enable USB device/gadget support. This allows the user to type e.g.
"ums 0 mmc 0" at the command-line to cause U-Boot to act a USB device
implementing the USB Mass Storage protocol, and expose MMC device 0
that way.
This allows a host PC to mount the Tegra device's MMC, partition it, and
install a filesystem on it.
