ALSA: HDA: export process_unsol_events() which can be used without

Browse Source 
hdac_bus library.

In some cases, we want to initialize hda bus without this hdac_bus
library(e.g. for non-HDA I2S only usuage on Intel Skylake+ platforms),
where we will do hdac bus non-HDA-only implementation in BSD license.

When we want to add hda link support(GPL) in this implementation, we
need reuse this process_unsol_events(), so export it is better solution
comparing to implement it again.
