ramips: add support for Linksys E7350

Linksys E7350 is an 802.11ax (Wi-Fi 6) router, based on MediaTek MT7621A. Specifications: - SoC: MT7621 (880MHz, 2 Cores) - RAM: 256 MB - Flash: 128 MB NAND - Wi-Fi: - MT7915D: 2.4/5 GHz (DBDC) - Ethernet: 5x 1GiE MT7530 - USB: 1x USB 3.0 - UART: J4 (57600 baud) - Pinout: [3V3] (TXD) (RXD) (blank) (GND) Notes: * This device has a dual-boot partition scheme, but this firmware works only on boot partition 1. Installation: Upload the generated factory.bin image via the stock web firmware updater. Signed-off-by: Rosen Penev <rosenp@gmail.com>
