ramips: add support for ZyXEL NWA50AX / NWA55AXE
Hardware
--------
CPU:    Mediatek MT7621
RAM:    256M DDR3
FLASH:  128M NAND
ETH:    1x Gigabit Ethernet
WiFi:   Mediatek MT7915 (2.4/5GHz 802.11ax 2x2 DBDC)
BTN:    1x Reset (NWA50AX only)
LED:    1x Multi-Color (NWA50AX only)

UART Console
------------
NWA50AX:
Available below the rubber cover next to the ethernet port.
NWA55AXE:
Available on the board when disassembling the device.

Settings: 115200 8N1

Layout:

<12V> <LAN> GND-RX-TX-VCC

Logic-Level is 3V3. Don't connect VCC to your UART adapter!

Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.

As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.

If the currently installed image is started from Slot A, the device will
flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case
and the device will return to the ZyXEL firmware upon next boot.

If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.

Installation TFTP
-----------------
This installation routine is especially useful in case
 * unknown device password (NWA55AXE lacks reset button)
 * bricked device

Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.

The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.

Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to owrt.bin

 $ atnf owrt.bin
 $ atna 192.168.1.88
 $ atns "192.168.1.66; tftpboot; bootm"

Upon booting, set the booted image to the correct slot:

 $ zyxel-bootconfig /dev/mtd10 get-status
 $ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
 $ zyxel-bootconfig /dev/mtd10 set-active-image 0

Copy the OpenWrt ramboot-factory image to the device using scp.
Write the factory image to NAND and reboot the device.

 $ mtd write ramboot-factory.bin firmware
 $ reboot
