mediatek: add support for netis NX31

Browse Source 
This PR adds support for netis NX31 router.

Specification
-------------
- SoC       : MediaTek MT7981BA dual-core ARM Cortex-A53 1.3 GHz
- RAM       : 256 MiB DDR3
- Flash     : SPI-NAND 128 MiB (ESMT)
- WLAN      : MediaTek MT7976CN dual-band WiFi 6
  - 2.4 GHz : b/g/n/ax, MIMO 2x2
  - 5 GHz   : a/n/ac/ax, MIMO 2x2
- Ethernet  : 10/100/1000 Mbps x3 (LAN, MediaTek MT7531AE)
              10/100/1000 Mbps x1 (WAN, SoC internal phy)
- USB       : No
- Buttons   : Mesh, Reset
- LEDs      : 1x Power (blue), unmanaged
              1x Status (blue), gpio-controlled
              1x WiFi 2.4 GHz (blue), gpio-controlled
              1x WiFi 5 GHz (blue), gpio-controlled
              3x LAN activity (blue), switch-controlled
              1x WAN activity (blue), gpio-controlled
- Power     : 12 VDC, 1 A

Installation
------------
1. Connect to the router using ssh (user: admin, pass: web interface
   password)
2. Make mtd backup:
   cat /dev/mtd0 | gzip -1 -c > /tmp/mtd0_spi0.0.bin.gz
   cat /dev/mtd1 | gzip -1 -c > /tmp/mtd1_BL2.bin.gz
   cat /dev/mtd2 | gzip -1 -c > /tmp/mtd2_u-boot-env.bin.gz
   cat /dev/mtd3 | gzip -1 -c > /tmp/mtd3_Factory.bin.gz
   cat /dev/mtd4 | gzip -1 -c > /tmp/mtd4_FIP.bin.gz
   cat /dev/mtd5 | gzip -1 -c > /tmp/mtd5_ubi.bin.gz
3. Download mtd backup from the /tmp dir of the router to your PC using
   scp protocol
4. Upload OpenWrt 'bl31-uboot.fip', 'preloader.bin' images to the /tmp
   dir of the router using scp protocol
5. Write FIP and BL2 (replace bootloader):
   mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-bl31-uboot.fip FIP
   mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-preloader.bin BL2
6. Place OpenWrt
   'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on
   the tftp server (IP: 192.168.1.254)
7. Erase 'ubi' partition and reboot the router:
   mtd erase ubi
   reboot
8. U-Boot automatically boot OpenWrt recovery image from tftp server to
   the RAM
9. Upload OpenWrt 'sysupgrade.itb' image to the /tmp dir of the router
   (IP: 192.168.1.1) using scp protocol
10. Connect to the router using ssh and run:
    sysupgrade -n openwrt-mediatek-filogic-netis_nx31-squashfs-sysupgrade.itb

Return to stock
---------------
1. Unpack stock BL2 and FIP partitions backup
2. Upload stock BL2 and FIP partitions backup to the /tmp dir of the
   router using scp protocol
3. Connect to the router using ssh and run:
   apk update && apk add kmod-mtd-rw
   insmod mtd-rw i_want_a_brick=1
   mtd unlock BL2
   mtd unlock FIP
4. Restore backup:
   mtd write /tmp/mtd4_FIP.bin FIP
   mtd write /tmp/mtd1_BL2.bin BL2
5. Erase ubi and reboot:
   mtd erase ubi
   reboot
6. Power off the router
7. Press Reset button and power on the router. Release the button after
   ~10 sec
8. Navigate to U-Boot recovery web server (http://192.168.1.1/) and
   upload the OEM firmware

Recovery
--------
1. Place OpenWrt
   'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on
   the tftp server (IP: 192.168.1.254)
2. Press “Reset” button and power on the router. After ~10 sec release
   the button.
3. Use OpenWrt initramfs system for recovery

MAC addresses
-------------
