ramips: add support for Asus RT-AC1200

Browse Source 
Asus RT-AC1200 is a 2.4/5GHz dual band AC router,
based on MediaTek MT7628AN.

Specification:
* SoC: MT7628AN
* RAM: DDR2 64 MiB
* Flash: 16 MiB NOR (W25Q128BV)
* Wi-Fi:
  * 2.4GHz: SoC Built-in
  * 5GHz: MT7612EN
* Ethernet: 5x 100Mbps
  * Switch: SoC built-in
* USB: 1x 2.0

Flash Layout:
 0x0000000-0x0030000 : "bootloader"
 0x0030000-0x0040000 : "nvram"
 0x0040000-0x0050000 : "factory"
 0x0050000-0x1000000 : "firmware"

MAC address:
 LAN: factory 0x28
 WAN: factory 0x22
 2.4G: factory 0x4
 5G: factory 0x8004

Installation via **recovery** mode:
1. Download the Asus recovery firmware (windows) tool from
   http://dlcdnet.asus.com/pub/ASUS/LiveUpdate/Release/Wireless/Rescue.zip
2. Set your ethernet IP manually 192.168.1.5 / 255.255.255.0 with NO
   gateway.
3. Plug in your ethernet to LAN port 1 on the router.
4. Load up the recovery software with the firmware file, but don't press
   "Upload" yet.
5. Plug in the router to power WHILE HOLDING the reset button in. While
   CONTINUING to hold the button, select "Upload" Continue to hold the
   reset button in until it finishes and verifies!
6. If that doesn't work try pressing "Upload" first just before you do
   step 5. At some point while holding reset the rescue tool will finally
   detect and upload the firmware. That's when you can let go of the
   reset button.
7. The router will reboot and not much will happen. Wait a minute or 2.
8. Power off and on the router again. Voila. Set everything your Ethernet
   IP back to DHCP (automatically) and you're good to go.

Revert to stock firmware:
1. Install stock image via recovery mode.
