ASoC: SOF: Introduce generic (in)firmware tracing infrastructure

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>
From the kernel point of view there are only few ops that needs to be exposed:

Hi,

SOF is using dma-trace (or dtrace) as a firmware tracing method, which is only
supported with IPC3 and it is not applicable for IPC4.

Currently the dtrace is 'open managed' regardless of IPC version (we do force
disable it for IPC4, but the dtrace calls remain in place).

From the kernel point of view there are only few ops that needs to be exposed
by the firmware tracing support and everything else is IPC private, should not
be known by the core.

This series converts the current dma-trace as ipc3 specific firmware tracing
sub-component and moves all private data out from generic code.

Regards,
Peter
