mediatek: add support for OpenEmbed SOM7981
Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: 256 MiB SPI-NAND, 32 GB eMMC optional RAM: 0.5/1 GB DDR4 Ethernet: 1x 1GbE, 1x 2.5GbE (RTL8221B) WiFi: MediaTek MT7976C USB: 1x USB 3.0 GPIO: 26-Pin header UART: 6 GND, 8 TX, 10 RX (in Pin header) Button: Reset, WPS Power: Type-C PD Installation: The board comes with a third-party custom OpenWrt image, you can upload sysupgrade image via LuCI directly WITHOUT keeping configurations. Or power on the board with pressing reset button for 5 second, then visit http://192.168.1.1 and upload -factory.bin firmware. Signed-off-by: Tianling Shen <cnsztl@gmail.com>
