sof-soundwire: rt711-sdca: set PGA30.0 volume in BootSequence

Browse source 
No sound from headphone jack on Dell Precision 5480, Ubuntu 24.04.4 LTS kernel version 6.17.0-20-generic

The SOF DSP pipeline volume PGA30.0 (pipeline 30, PCM device 0) defaults
to 0 at boot, which the dBscale treats as a hardware mute. The DAPM chain
is active and audio flows on the SoundWire bus, but the pipeline passes
silence into the codec.

Set PGA30.0 30 Playback Volume to 32,32 (0 dB) so the pipeline is not
muted when headphones are enabled. Software volume is applied on top by
PipeWire/PulseAudio independently.

Tested on Dell Precision 5480 (Intel Raptor Lake-P, rt711-sdca on
SoundWire master-0-2).
