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. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
