ath79: add support for MikroTik RouterBOARD 921GS-5HPacD-15s

The MikroTik RouterBOARD 921GS-5HPacD-15s (mANTBox 15s) is an outdoor
antenna for 5 GHz with an built-in router. This ports the board from
ar71xx.

See https://mikrotik.com/product/RB921GS-5HPacD-15S for more info.

Specifications:
 - SoC: Qualcomm Atheros QCA9558 (720 MHz)
 - RAM: 128 MB
 - Storage: 128 MB NAND
 - Wireless: external QCA9892 802.11a/ac 2x2:2
 - Ethernet: 1x 1000/100/10 Mbps, integrated, via AR8031 PHY, passive PoE in
 - SFP: 1x host

Working:
 - NAND storage detection
 - Ethernet
 - Wireless
 - 1x user LED (blinks during boot, sysupgrade)
 - Reset button
 - Sysupgrade

Untested:
 - SFP cage (probably not working)

Installation (untested):
 - Boot initramfs image via TFTP and then flash sysupgrade image

As the embedded RB921-pcb is a stripped down version of the RB922 this patch
adds a common dtsi for this series and includes this to the final dts-files.
