ramips: add support for Ruijie RG-EW1300G (V1.00)

The RG-EW1300G is a router with 1 x WAN and 3 x LAN gigabit ports.
The router runs on Ruijie OS by default.

- Specifications:

* SoC: MT7621A
* RAM: 128MB DDR3
* Flash: 16MB SPI NOR flash (GD25Q128C)
* WiFi0: Mediatek MT7615 2.4GHz 802.11b/g/n
* WiFi1: Mediatek MT7615 5GHz 802.11ac
* Ethernet: MT7530, 4x 1000Base-T.
* UART: Serial console - As marked on PCB, baudrate is 57600. DO NOT CONNECT 3.3V.
* Buttons: Reset, WPS.
* LED: Programmable LEDs via GPIO working for Red+Green status, and Mesh/WPS at the rear of the chassis.

- Default Flash:

```

- Installation:

1. Open the case, solder to the marked 4 pin header
2. Connect it to a USB-UART TTL (do not connect to 3.3v)
3. Open a terminal with baud 57600.
4. Power on device, and repeatedly press "2" key to catch bootloader option
5. Set IP, TFTP server IP, and image file to load (eg, openwrt-ramips-mt7621-ruijie_rg-ew1300g-v1-squashfs-sysupgrade.bin)
6. System will reboot into OpenWRT.
