ramips: add support for Netgear R6020
This adds support for the Netgear R6020, aka Netgear AC750. The R6020 appears to be the same hardware as the Netgear R6080, aka Netgear AC1000, but it has a slightly different flash layout, and no USB ports. Specification: SoC: MediaTek MT7628 (580 MHz) Flash: 8 MiB RAM: 64 MiB Wireless: 2.4Ghz (builtin) and 5Ghz (MT7612E) LAN speed: 10/100 LAN ports: 4 WAN speed: 10/100 WAN ports: 1 UART (57600 8N1) on PCB MAC addresses based on vendor firmware: LAN *:88 0x4 WAN *:89 WLAN2 *:88 0x4 WLAN5 *:8a 0x8004 The factory partition might have been corrupted beforehand. However, the comparison of vendor firmware and OpenWrt still allowed to retrieve a meaningful assignment that also matches the other similar devices. Installation: Flashing OpenWRT from stock firmware requires nmrpflash. Use an ethernet cable to connect to LAN port 1 of the R6020, and power the R6020 off. From the connected workstation, run `nmrpflash -i eth0 -f openwrt-ramips-mt76x8-netgear_r6020-squashfs-factory.img`, replacing eth0 with the appropriate interface (can be identified by running `nmrpflash -L`). Then power on the R6020. After flashing has finished, power cycle the R6020, and it will boot into OpenWRT. Once OpenWRT has been installed, subsequent flashes can use the web interface and sysupgrade files.
