    ath79: add support for ZiKing CPE46B
    
    ZiKing CPE46B is a POE outdoor 2.4ghz device with an integrated directional
    antenna. It is low cost and mostly available via Aliexpress, references can
    be found at:
    - https://forum.openwrt.org/t/anddear-ziking-cpe46b-ar9331-ap121/60383
    - https://git.lsd.cat/g/openwrt-cpe46b
    
    Specifications:
    
    - Atheros AR9330
    - 32MB of RAM
    - 8MB of flash (SPI NOR)
    - 1 * 2.4ghz integrated antenna
    - 2 * 10/100/1000 ethernet ports (1 POE)
    - 3 * Green LEDs controlled by the SoC
    - 3 * Green LEDs controlled via GPIO
    - 1 * Reset Button controlled via GPIO
    - 1 * 4 pin serial header on the PCB
    - Outdoor packaging
    
    Flashing instruction:
    
    You can use sysupgrade image directly in vendor firmware which is based
    on OpenWrt/LEDE. In case of issues with the vendor GUI, the vendor
    Telnet console is vulnerable to command injection and can be used to gain
    a shell directly on the OEM OpenWrt distribution.

    [fix whitespaces, drop redundant uart status and serial0, drop
    num-chipselects, drop 0x1002 MAC address for wmac]
