Refcounting is used to track ALH block usage and to
call alh_claim_ownership()/alh_release_ownership() accordingly.
This is however incorrectly done on ALH instance basis, which
means when one instance is released, ownership can be released
even though one ALH instance is still active.
Fix the logic by tracking ALH usage as a global property
which matches the alh_claim_ownership/alh_release_ownership
semantics.

Modify dai_config_get function to have the config struct as argument.
This was not a showstopper but a request in the API review.
In the same patch modify all Intel dai drivers using the API to preserve
bisect/compile.

The ALH is an intermediary device, which acts as a hub and provides an
abstracted support for numerous sound interfaces (e.g. SoundWire).
