ASoC: SOF: enable multicore with dynamic pipelines

Merge series from Kai Vehmanen <kai.vehmanen@linux.intel.com>:

	When a pipeline is marked dynamic in the SOF DSP firmware
	topology definition (the tplg file kernel loads from filesystem),
	it means the pipeline resources are not allocated when DSP is
	booted (at driver probe, or at runtime resume), but rather delayed
	until the pipeline is actually used.
