alsa-ucm: Use playback/capture rate specification from UCM

Browse source 
Add new PlaybackRate/CaptureRate values for UCM that can be used to
specify custom rates for devices. This value can either be set on the
verb, which makes it apply to all devices, or on the device to override
the verb setting.
