Mikrotik RB951 router has a buzzer on the board, which makes annoying noises
due to the interference caused by PoE input or Wifi transmission
when no GPIO pin state is set.
I added buzzer node to device's DTS in order to set deault level to 1
and to provide easier access for it.

MikroTik RB951G-2HnD is a wireless SOHO router that was previously
supported by the ar71xx target, see commit 7a709573d7 ("ar71xx: add
kernel support for the Mikrotik RB951G board").

- 1x PoE in (port 1, 8-30 V input)
- Wireless: Atheros AR9340 (802.11b/g/n)
- USB: 2.0 (1A)

Unlike on the RB951Ui-2HnD, none of the LEDs on this device seem to be
GPIO-controllable, which was also the case for older OpenWRT versions
that supported this board via a mach file. The Ethernet port LEDs are
controlled by the switch chip.

Flashing
--------
TFTP boot initramfs image and then perform sysupgrade. Follow
