[PATCH] arm: sun8i: nanopi-neo: Enable USB OTG

[David Disseldorp <ddiss-l3A5Bk7waGM@public.gmane.org>]

From: David Disseldorp <ddiss-eUNUBHrolfbYtjvyW6yDsg@public.gmane.org>

The NanoPi NEO features a MicroUSB port that can work in both host mode
and peripheral mode. Switching is handled via GPIO PG12.
