On platforms which have smart speaker amplifiers connected via

use the runtime stream to setup slave streams.
soundwire already as a set function, get function would provide more
flexibility to above configurations.

So who would be calling this API? Machine or someone else?
From Machine driver in my case where smart speaker amplifiers are
modeled as aux device which is also dai less.
