Add sound node and dsp-related piece to enable HDMI audio
playback support on Qualcomm QRB4210 RB2 board. That is the
only sound output supported for now.

The audio playback is verified using the following commands:

amixer -c0 cset iface=MIXER,name='SEC_MI2S_RX Audio Mixer MultiMedia1' 1
aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Center.wav
