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