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.

Drop redundant else.
Not all the dai drivers would implement this function, I guess else is not redundant here!

Eh. By that I meant dropping "else" keyword and reducing indentation for "return ERR_PTR(-ENOTSUPP);"
