[PATCH 9/9] ARM: dts: sun7i: bananapi-m1-plus: Enable USB OTG

[Chen-Yu Tsai <wens@xxxxxxxx>]

The Bananapi M1+ supports USB OTG, with the PMIC doing VBUS sensing.

Enable the USB OTG related functions. This also enables the previously
missing USB PHY node, which also handles some initial setup for the
normal USB hosts.
