ASoC: SOF: topology: Use partial match for connecting DAI link and DAI widget

This allows setting shorter names for the widget stream names in
topology. For example, in the case of HDA Analog DAI link, the stream
name is "Analog Playback and Capture". But it is enough to match "Analog"
in the DAI link stream name with a widget's stream name. This is needed
to set more meaningful names for the DAI widgets using the stream name
in topology.
