ramips: add support for Cudy M1800

Specifications SoC: MT7621 CPU: 880 MHz Flash: 32 MiB RAM: 256 MiB WLAN: MT7915 WiFi 6 (2.4/5 GHz) Ethernet: 2x Gbit ports MAC LAN b4:4b:d6:2e:c7:b0 (label) WAN b4:4b:d6:2e:c7:b1 WiFi 2.4 00:0c:43:26:46:08 WiFi 5 00:0c:43:26:59:97 Installation There are two known options: 1) The Luci-based UI. 2) Press and hold the reset button during power up. The router will request 'recovery.bin' from a TFTP server at 192.168.1.88. Both options require a signed firmware binary. The openwrt image supplied by cudy is signed and can be used to install unsigned images. Signed-off-by: Leon M. Busch-George <leon@georgemail.eu>
