The simple-audio-card's microphone widget currently connects to the
headphone jack. Routing the microphone input to the microphone jack
allows for independent operation of the microphone and headphones.

This resolves the following boot-time kernel log message, which
indicated a conflict when the microphone and headphone functions were
not separated:
  debugfs: File 'Headphone Jack' in directory 'dapm' already present!
