Subject: [PATCH 4.9 080/206] ARM: dts: sun7i: bananapi-m1-plus: Enable USB PHY for USB host support

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chen-Yu Tsai <wens@...e.org>

commit 0cff18cbab4f55581d9da86e4286655d9723d7d2 upstream.

The 2 USB host ports are directly tied to the 2 USB hosts in the SoC.
The 2 host pairs were already enabled, but the USB PHY wasn't.
VBUS on the 2 ports are always on.

Enable the USB PHY.

		      board")
