hw: add "min_rate" and "max_rate" as alternatives to single "rate" parameter

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #191 was opened from bku-sue:

Our typical use case is to limit the rate to between 44100 and 48000, as with these boundaries the resampling becomes easier, than if only allowing 48000.
