ASoC: SOF: sof-audio: add support for setting up loopback routes 
During route setup, playback stream routes are setup by going through
sink path, capture stream routes are set up by going through source path.
This is not sufficient to handle loopback cases between pipelines
configured with different directions, e.g. a sidetone or an amplifier
feedback connected to a speaker protection module. So, add the logic to
handle such routes between widgets that aren't in the list of DAPM widgets
associated with the same PCM.
