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.
