I don't know how dts instances both in mainline, but I would think if
you create two musb instances, and load a gadget driver for this micro
USB port, the USB host should enumerate it. The standard port should
be the 2nd instance which has its ID pin grounded and work in
host-only mode.

This is how they work in TI 3.2 kernel.
