hal-bt: Enrich 'halmixer' section in plugin init

Enrich 'halmixer' section with bluetooth specific 'source' and 'stream'
during hal-bt plugin initialization.
Some parameters must be passed to plugin using 'params' key in controller
json plugin section.
This allows to get rid of must of the additional configuration when using
bluetooth in a hal.
