ASoC: soc-acpi: add get_function_tplg_files ops

[ Upstream commit d1e70eed ]

We always use a single topology that contains all PCM devices belonging
to a machine configuration.
However, with SDCA, we want to be able to load function topologies based
on the supported device functions. This change is in preparation for
loading those function topologies.
