mediatek: add support for TP-Link TL-7DR7250

Hardware specification: SoC: MediaTek MT7988D 3x A73 Flash: 128 MB SPI-NAND (F50L141LB / DS35Q1GB) RAM: 512 MB DDR4 (NT5AD256M16E4-JR) Ethernet: 2x 1GbE (built-in), 2x 2.5GbE (built-in + Airoha EN8811HN) WiFi: MediaTek MT7992A Button: Reset, Mesh Power: DC 12V 2A UART: 3.3v, 115200n8 Flash instruction: TP-Link locks down their firmware and serial console, so the firmware must be flashed with mtk_uartboot. 1. Download mtk_uartboot: https://github.com/981213/mtk_uartboot/releases 2. Open the case, and attach to the UART. 3. Start mtk_uartboot: ./mtk_uartboot -a -s /dev/ttyUSB0 -p mt7988-ram-ddr4-bl2.bin \ -f immortalwrt-mediatek-filogic-tplink_tl-7dr7250-v1-bl31-uboot.fip \ --brom-load-baudrate 921600 --bl2-load-baudrate 1500000 5. Cut off the power and re-engage, wait for UART download to complete. 6. Connect to the UART, write new BL2/FIP/Firmware with TFTP. Signed-off-by: Tianling Shen <cnsztl@immortalwrt.org>
