audio: cs42l73: Fix capture widget map issues

BZ: 30339 27806 32448

The DAPM map for the capture path in the codec had a common Mic widget for both
DMIC and AMIC. Also, the multiplexing was not set up properly, as a result of
which the AMIC path was also getting enabled on DMIC recording.

Fix by providing separate DMICA, DMICB widgets for DMICs and setting up the Mux
widget properly. The Mux widget selects the path (AMIC, DMIC) based on the ALSA
mixer settings set by HAL.

This changes the ALSA mixer interface and needs a fix in the HAL layer for
recording to work properly. The HAL layer should use the new mixers provided for
recording instead of the earlier mixers.
