ASoC: SOF: Intel: mtl: Enable multicore support

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

The following series will enable multicore support on MTL platforms similarly
to other Intel platforms.

The TGL patch is included to simplify the core_put implementation.

Multicore support can be enabled by updated topologies, with current set of
tplg files this series is not introducing any runtime change.
