ath79: add support for Comfast CF-EW71 v2 Specifications: Qualcomm/Atheros QCA9531 2x 10/100 Mbps Ethernet, with 48v PoE 2T2R 2.4 GHz, 802.11b/g/n 128MB RAM 16MB SPI Flash 4x LED (Always On Power, LAN, WAN, WLAN) Flashing instructions: The original firmware is based on OpenWrt, so flashing the sysupgrade image over the factory firmware is sufficient. The bootloader has a built-in recovery web-ui. This is the method I used to flash OpenWrt. You can get to the recovery web-ui by holding down the reset button for a few seconds (~5s) while pluggin in the router. The LEDs should start blinking fast and the router should be available on 192.168.1.1 for the recovery. Tested: Reset button, WAN LED, LAN LED, Power LED (always on, not much to test), WLAN LED, MAC addresses (same as factory firmware). Signed-off-by: Felix Golatofski
