[PATCH v4 7/9] arm: dts: mt7623: enable the usb device on the mt7623n rfb

[sean.wang at mediatek.com]

From: John Crispin <john at phrozen.org>

All versions of the mt7623n RFB have an USB port so enable the device.
There is a gpio that gets used to power up the port supply. Add support
for this gpio using the fixed-regulator driver.
