ar71xx: wndr4300: enable 5V power for the USB port
The 5V power of the USB is controlled by a GPIO pin of
the external WiFi chip. Setup the GPIO bitmasks in the
platform data of the WiFi chip to ensure that the 5V
power gets enabled by the ath9k driver.
Based on the the WNDR3700v4 support patch from Ralph Perlich:
