ramips: add support for Netgear EX6130

Specifications:
* SoC: MT7620A
* RAM: 64 MB DDR
* Flash: 8MB NOR SPI flash
* WiFi: MT7612E (5Ghz) and builtin MT7620A (2.4GHz)
* LAN: 1x100M

The -factory images can be flashed from the
device's web interface or via nmrpflash.

The device seems to use base PCB as EX3700/EX3800,
but supporting AC1200 using MT7612E.

MAC adresses:
5.0 GHz  0x8004  *:9a
2.4 GHz  0x4     *:9b
lan      0x28    *:9b
wan      0x2e    *:9c

Since this is a one-port device, although wan MAC address is
set in flash, it is not used in OpenWrt setup.
