On platforms which have smart speaker amplifiers connected via
soundwire and modeled as aux devices in ASoC, in such usecases machine
driver should be able to get sdw master stream from dai so that it can
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.
