Add proper audio routes for onboard analogue microphones AMIC[1345] -
MIC biases and route from TX macro codec to WCD9385 audio codec.

This finally brings AMIC1, AMIC3, AMIC4 and AMIC5 onboard microphones to
work.  AMIC2 (headphones) should be fine well, however it didn't work
during tests, probably because of incomplete USB switch.
