PATCH 1/1 ARM: tegra: enable USB device mode port on Dalmore

From: Stephen Warren <[email protected]>

This allows U-Boot to expose UMS and DFU protocols on this port in device mode, or to act as a USB host on the port, using an "OTG" (micro-B to female A host) cable.

This shouldn't be needed with driver model (CONFIG_DM_USB). What effect does it have?

It might have no effect. However, I added it to keep the content of all Tegra config headers identical (at least those that enable USB device mode w.r.t. this line). Perhaps this line should be removed from all the other headers too?
