ASoC: SOF: reduce default verbosity of IPC logs

Browse Source 
We currently log the initiation of an IPC as well at its success.

[ 3906.106987] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx: 0x80010000: GLB_DAI_MSG: CONFIG
[ 3906.107189] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx succeeded: 0x80010000: GLB_DAI_MSG: CONFIG

This is overkill in most cases, we already have a message thrown in
case of errors and have tracepoints enabled to check for IPC
duration. The only case where this might be useful is to check if
there is an interleaved IPC RX. Add a flag and only print those logs
if enabled.

In addition, the DMA_POSITION_UPDATE for traces brings limited
information in most cases and pollutes the logs for no good reason.

[ 3906.322256] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc rx: 0x90020000: GLB_TRACE_MSG: DMA_POSITION

[ 3907.822261] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc rx: 0x90020000: GLB_TRACE_MSG: DMA_POSITION
[ 3907.822319] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc rx done: 0x90020000: GLB_TRACE_MSG: DMA_POSITION
[ 3908.822251] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc rx: 0x90020000: GLB_TRACE_MSG: DMA_POSITION
[ 3908.822309] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc rx done: 0x90020000: GLB_TRACE_MSG: DMA_POSITION

This information is only helpful when debugging the trace support, not
when using the trace. Add a flag to only print DMA position update
logs if enabled.
