hal: configure the path for flicker sensor 

Flicker sensor / rainbow sensor is connected to audio codec
on SDM845.

This change configures how the flicker sensor data
is rounted from AMIC1 to HAL. It has no impact on power consumption.

Camera HAL uses pcm_read to enable the the data path in camera use cases.

Bug: 77698944
Test: audio recording and playback
