ASoC: SOF: Intel: hda: add callback to check SoundWire lcount information
The number of links is stored in different registers depending on the
IP version, add sdw_check_lcount() callback. This callback only checks
that the number of links supported in hardware is compatible with the
number of links exposed in ACPI _DSD properties.
