ath79: add support for D-Link DAP-3320 A1

Specifications:
 * QCA9533, 16 MiB Flash, 64 MiB RAM, 802.11n 2T2R
 * 10/100 Ethernet Port, 802.11af PoE
 * IP55 pole-mountable outdoor case

Installation:
 * Factory Web UI is at 192.168.0.50
   login with 'admin' and blank password, flash factory.bin
 * Recovery Web UI is at 192.168.0.50
   connect network cable, hold reset button during power-on and keep it
   pressed until uploading has started (only required when checksum is ok,
   e.g. for reverting back to oem firmware), flash factory.bin

After flashing factory.bin, additional free space can be reclaimed by
flashing sysupgrade.bin, since the factory image requires some padding
to be accepted for upgrading via OEM Web UI.
