lib: dai: Fix dai_get_device

dai_get_device is called using DAI-types from IPC definition
but calls dai_config_get() which returns a Zephyr DAI type.

So, in order to fix this, we introduce `dai_type_to_zephyr`
which converts a DAI-type from IPC definition to a Zephyr DAI
type, so that later we can compare types in the same space.

The current code works because the two DAI types are matching,
but it is no longer the case with latest introduces types.
