firmware: Use DMA40 for PWM audio


Dec 28 01:57:14 twofar pulseaudio[851]: E: [alsa-sink-bcm2835 Headphones] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write.
Dec 28 01:57:14 twofar pulseaudio[851]: E: [alsa-sink-bcm2835 Headphones] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_bcm2835'. Please report this issue to the ALSA developers.
Dec 28 01:57:14 twofar pulseaudio[851]: E: [alsa-sink-bcm2835 Headphones] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
