ASoC: Kona: Avoid static route between cpu and codec dai 



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 first
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. Set the dynamic bit of
backend dai dailink to update the backend parameters
before codec path setup.
