ASoC: SOF: Intel: hda: Skip interfaces not supported on a platform
Not all interfaces (SSP/DMIC/HDA/SDW) are available on all platforms. If the interface is not even supported then there is no point in executing a probe or query for that interface. Introduce a simple function (hda_get_interface_mask) to query the interfaces supported on the platform.
