Subject: ath79: add support for Ubiquiti UniFi AP Pro

This adds support for the Ubiquiti UniFi AP Pro to the ath79 target. The
device was previously supported on the now removed ar71xx target.

SoC   Atheros AR9344
WiFi  Atheros AR9344 & Atheros AR9280
ETH   Atheros AR8327
RAM   128M DDR2
FLASH 16M SPI-NOR

Installation
------------

Follow the Ubiquiti TFTP recovery procedure for this device.

1. Hold down the reset button while connecting power for 10 seconds.
2. Transfer the factory image via TFTP to the AP (192.168.1.20)
3. Wait 2 minutes for the AP to write the firmware to flash. The device
   will automatically reboot to OpenWrt.
