qualcommax: ipq807x: add Zyxel NWA110AX support

The Zyxel NWA110AX is a dual band 2x2:2 802.11ax wireless access point
with PoE.

The device is very similar to the NWA210AX except for being 2x2 instead
of 4x4 in the 5GHz band and not having the 2.5GbE ethernet port. This
commit factors out a common DTS and device definition and reuses it for
both devices.

Hardware:
* SoC: Qualcomm IPQ8070A
* RAM: 1GiB 1x Samsung K4A8G165WC-BCTD
* Flash: 8MiB Winbond W25Q64DW SPI-NOR, 256MiB Winbond W29N02GZ SPI-NAND
* WLAN 2.4GHz: QCN5024 2x2:2 802.11b/g/n/ax
* WLAN 5GHz: QCN5054 2x2:2 802.11n/ac/ax
* Ethernet: 1x 1GbE with AR8033 PHY
* Serial Config: 3.3V TTL 115200-8-N-1, externally accessible
* Serial Layout: GND TX RX 3.3V (don't connect, marked with triangle)
* LEDs: 1x red, 1x green, 1x blue, 1x white
* Buttons: 1x reset

MAC addresses:
* Uplink: base address on label
* 2.4GHz WLAN: base + 1
* 5GHZ WLAN: base + 2

Flashing Notes:
The device uses a dual-image setup and OpenWrt can only be installed as
image 0. When the currently running stock firmware is image 0, OpenWrt
will be installed as image 1, fail to boot and the device returns to stock
firmware. If this happens, install any version of stock firmware so that
it runs as image 1, before installing OpenWrt. Alternatively, if there
already is a valid stock firmware in image 1, the "debug dual-image show"
and "debug dual-image set boot-image image1" commands can be used in the
stock CLI via serial/SSH/telnet to switch to image 1.

Flashing with Stock Web Interface:
* Get the OpenWrt factory image and rename it to a shorter name, for
  example "openwrt.bin" (the stock firmware has a character limit)
* In the web interface, go to "Maintenance" -> "File Manager" ->
  "Firmware Package" (or click the link next to "Firmware Version" under
  "Device Information" on the dashboard)
* Under "Upload File" browse to the renamed OpenWrt factory image and
  click on "Upload"

Switch Boot Image:
* OpenWrt to stock: "zyxel-bootconfig-ipq807x set image1"
* Stock to OpenWrt: "debug dual-image set boot-image image0"

Unbrick / Revert to Stock with the Boot Module:
* Disconnect the device from power
* Configure your machine to 192.168.1.103/24 and start a TFTP server
* Put the stock firmware image into the TFTP server root and rename it to
  "ZLD-current"
* Establish a serial connection to the device through the console port
* Connect the device to power
* When prompted, press a key to abort automatic boot and enter debug mode
* Use the "atnz" command to flash the firmware image
* Use the "atgo" command to boot from the newly flashed image
