mediatek: filogic: add Acelink EW-7886CAX support
Acelink EW-7886CAX is an MT7986A (AKA Filogic 830) based access point. It has 512 MiB of RAM, one 2.5 Gbps PoE (802.3at) Ethernet port and on-SoC Wi-Fi. There is no printed MAC label (on my unit). My unit came with Mediatek's firmware (based on OpenWrt 21.02) installed. It was possible to simply upgrade using OpenWrt's sysupgrade tool. Another verified upgrade method is using U-Boot (requires UART). During every boot there is "U-Boot Boot Menu". Selecting option "2. Upgrade firmware" allows using U-Boot's tftp client to load and flash factory image. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
