[PATCH v3 7/9] arm: dts: mt7623: enable the usb device on the mt7623n rfb

[sean.wang]

From: John Crispin <j...@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.
