ANDROID: GKI: ASoC: dapm: Avoid static route b/w cpu and codec dai

Browse Source 
Currently ASoC core creates a static route b/w
playback/capture widgets of cpu and codec dai
if they are part of the same dai-link. However
this will cause codec path to get powered up
followed by the backend dai start during device
switch use-case where the front-end is not closed,
leading to audio playback failure if either bit-width
or sample rate is different.
