ath79: DTS improvement for buzzer on RB951G-2HnD

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.
