This patch sets missing stream_name of capture part of the DAI driver so we can define DAPM routing properly also for the capture stream.

While at it "Playback" suffix is added to the playback stream names to clearly identify playback/capture.

Together with related dts patch this fixes NULL pointer dereference when opening ALSA device for recording on Odroid XU3.
