    ath79: add support for MikroTik RouterBOARD 912UAG-2HPnD
    
    This board has been supported in the ar71xx.
    
    Links:
    * https://mikrotik.com/product/RB912UAG-2HPnD
    * https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-2hpnd
    
    This also supports the 5GHz flavour of the board.
    
    Hardware:
    * SoC: Atheros AR9342,
    * RAM: DDR 64MB,
    * SPI NOR: 64KB,
    * NAND: 128MB,
    * Ethernet: x1 10/100/1000 port with passive POE in,
    * Wi-Fi: 802.11 b/g/n,
    * PCIe,
    * USB: 2.0 EHCI controller, connected to mPCIe slot and a Type-A
      port -- both can be used for LTE modem, but only one can be
      used at any time.
    * LEDs: 5 general purpose LEDs (led1..led5), power LED, user LED,
      Ethernet phy LED,
    * Button,
    * Beeper.
    
    Not working:
    * Button: it shares gpio line 15 with NAND ALE and NAND IO7,
      and current drivers doesn't easily support this configuration,
    * Beeper: it is connected to bit 5 of a serial shift register
      (tested with sysfs led trigger timer). But kmod-gpio-beeper
      doesn't work -- we left this as is for now.
    
    Flashing:
    * Use the RouterBOARD Reset button to enable TFTP netboot,
    boot kernel and initramfs and then perform sysupgrade.
    * From ar71xx OpenWrt firmware run:
      $ sysupgrade -F /tmp/<sysupgrade.bin>
    For more info see: https://openwrt.org/toh/mikrotik/common.
