[WORKAROUND]audio: SW support to swap mic bias1 & bias2

BZ: 39873

Lex PR1.1 and PR2.1 have their AMIC bias lines are swapped.
Codec and Machine driver needs to handle the difference
between these two boards using SPID.

During driver initialization drivers reads SPID and based on
board, appropriate audio map is initialized.  In machine driver,
use appropriate AMIC Bias to handle headset button presses.

This patch should be reverted once Lex PR1.1 is EOLed.
