ramips: add support for C-Life XG1 [WIFI6] (#10057)

CPU: MediaTek MT7621AT
  Flash: Micron MT29F2G08ABAGAWP 128M
  RAM: 256 M
  WiFi: MT7915 2.4/5 GHz 2T2R
  Ethernet: 10/100/1000 Mbps x3
  LED: Status (red / blue / white / green / purple / cyan)
  USB: 2.0 x 1
  ZigBee/BlueTooth
  USB Audio: iec958 x 1
  Button: Reset
  Power: DC 12V,1.5A

开启ssh方法:
  打开网页:192.168.10.1,用户路由器底面标注的用户名密码完成登陆。
  然后打开网页:http://192.168.10.1/cgi-bin/luci/admin/mtk/console，在命令行中输入以下命令:
  echo -en "root\nroot\n" | passwd
  然后打开网页:http://192.168.10.1/cgi-bin/luci/pti/ssh_open
  即可ssh登陆192.168.10.1,用户名root,密码root

刷入openwrt:

开启ssh后，上传breed-mt7621-xiaomi-r3g.bin到路由器/tmp目录。
然后使用下面命令刷入breed:
mtd -r write /tmp/breed-mt7621-xiaomi-r3g.bin Bootloader
等待机器重启，等1分钟断开电源。
按住C-Life XG1机身正面的圆形IoT按钮(gpio 18),通电就能进入breed刷机.
