Enable 4-channel input
This requires adding channel remap functionality to input/output streams.
Number of channels provided by hardware might be different from what framework expects.
For example in case of Pixel C there is I2S bus to rt5677 codec shared by both capture and
playback. If we want to record 4-channel input from mics and playback stereo at the same time
then HW format has to be 4-channel (I2S cannot have different formats for capture/playback).
In such case we need to adjust number of audio channels.

Enable 4-channel input
Smaug has 4 microphones. Enable 4-channel input that will be processed to
2-channel by a noise-suppression module.
Kernel ALSA does not like when when open codec (in case of Smaug rt5677)
both for input and output with different format (2-channel TDM vs 4-channel TDM).
It confuses ALSA and it gets dropping half of all frames.
To avoid that we open output with 4-channel format as well and scatter data
2->4 channel somewhat reverse what we do at the input.

audio HAL: fix thread starvation
Fix thread starvation issue where the capture or playback threads
running in FIFO priority would constantly acquire the stream mutex preventing
other threads to complete routing commands.

audio hal: add sound trigger
Add a sound trigger library, this is used to support "OK Google" when
the device is asleep or running an app.
This is based on the Volantis code, modified to work with the hotword
trigger code that will be posted upstream.

Make capture buffer the same size as input buffer
Apps expect that input/output buffers are equal in size and it is part
of documented behavior for OpenSL ES on Android.
In the future we want to decrease both buffers to lower value. But for now
let's increase the capture one.
Bug: 25432061
Test: playback/capture works

audio hal: Decrease playback buffer size.
Cutting the playback buffer from 1024 to 512 enables fast mixer but
still provides extra underrun protection compared to 128.

size.
