[LEDE-DEV] [PATCH] ar71xx: add support for Comfast CF-E312A V2

The Comfast CF-E312A V2 is a 5 GHz radio with a built-in directional antenna,
much like a Ubiquiti NanoStation M5.

Specifiation:
- SoC: AR9344 at 650 MHz
- Flash: 16 MiB (W25Q128FVSG)
- RAM: 64 MiB DDR2 (W9751G6KB)
- Ethernet:  1 x WAN (100 Mbps) and 1 x LAN (100 Mbps)
- Button: 1 x reset button, 1 x PoE pass-through switch
- LED: 8 x LEDS (Power, LAN, WAN, Wireless, 4 signal LEDs)
- UART: 1 x UART with header on PCB (GND, RX, TX, 3.3V)

It is very similar to the CF-316N - similar chipset, etc. The major
differences are:

* It operates at 5 GHz, not 2.4
* All the LEDs are white
* It has 4 signal LEDs

Of note: the eth1 port has an optional PoE pass-through, controlled with a
slider switch.

Most of the changes are in the file
target/linux/ar71xx/files/arch/mips/ath79/mach-cf-e316n-v2.c - the code
for the E316N was copied and modified to support the additional LEDs, the
LED colors, and a few changes in the GPIOs.

Firmware can be flashed on these units by the following method:
1.) Apply power to the unit
2.) Immediately AFTER applying power, hold down the reset button
3.) The WAN, LAN, and wireless lights will flash - wait three seconds
(three flashes) and then release the button.
4.) After a second, the lights will "flutter" quickly and the unit will
be visible at 192.168.1.1. A web page will be available to enable quick
and simple uploading and flashing of firmware.

During the boot process, these units also look for a tftp server at
192.168.1.10. If one is present, the firmware can be uploaded as a file
called "firmware-auto.bin"
