ramips: Add suport for COMFAST CF-WR617AC

Specifications:
Chipset:MT7628DA+MT7612E
Antenna : 2.4Ghz:2x5dbi Antenna + 5.8Ghz:2x5dbi Antenna
Wireless Rate:2.4Ghz 300Mbps , 5.8Ghz 867Mbps
Output Power :100mW(20dbm)
Physical port:110/100Mbps RJ45 WAN Port , 310/100Mbps RJ45 LAN Port
Flash: 8Mb
DRam: 64Mb
Flashing: default bootloader attempts to boot from tftp://192.168.1.10/firmware_auto.bin using 192.168.1.1

Known issues:
mac-address-increment for 5GHZ doesnt work, i failed to figure out why. Original firmware using +1 from original value in factory partition.
