ASoC: SOF: topology: Add helper to get/put widget queue id

Browse Source 
Add get/put queue id helper to manage queue id in route
setup and route free.

The queue allocation rules are:

  - If widget only has one sink/source pin, zero will be
returned as the queue ID directly.

  - If widget has more than one sink/source pins, and pin
binding array is defined in topology, queue ID will be
allocated according to the pin binding array.

  - If widget has more than one sink/sink pins, and pin
binding array is not defined, Linux ID allocation will be
used to allocate queue ID dynamically.
