mixer: add support for pcm device specific mixer controls
Mixer control such as "Playback channel map" can be registered by multiple pcm device nodes and is distinguished by device in snd_ctl_elem_id. Add support to get the control handle associated with mixer ctl name and device number. Also, introduce API to get the device number associated with specific mixer_ctl handle.
