Add proper audio routes for onboard analogue microphones: AMIC[1345].
Use also new DAPM input widget (TX SWR_INPUTn) for them, not the
deprecated ADC one. Change is not compatible with older kernels not
having the new SWR_INPUTn input widget.

Depends on ASoC driver changes:

This patch should wait till respective ASoC changes got merged.

These should reflect the board-level wiring of MIC BIAS, are you sure
that this is how the hdk is wired up?
