audio: Kang audio HAL from amlogic yukawa device
Copied from device/amlogic/generic/hal/audio/ minus the
speaker equalizer filter file.
It is a generic and more feature rich HAL, plus it fixes
the occasional static noise we hear on db845c and PocoF1.
Removed the mixer control settings from qcom/init.qcom.rc
and added HDMI out mixer control in etc/mixer_paths.xml
to start with. ** Analog audio out is not tested yet. **
ToDo:
1. Fallback to Analog audio port if the monitor doesn't
support HDMI audio out.
2. Mic AEC support is integrated deep in this HAL, so I
didn't remove it. Might as well test and use that
feature on Pixel 3 and Poco F1. Same with speaker EQ,
though we may end up never using this equalizer
feature at all.

+ Each module will contain the following sections:
+ “devicePorts”: a list of device descriptors for all input and output devices accessible via this

+ This contains both permanently attached devices and removable devices.
+ “mixPorts”: listing all output and input streams exposed by the audio HAL
+ “routes”: list of possible connections between input and output devices or between stream and
+ devices.
+ "route": is defined by an attribute:
+ -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)
+ -"sink": the sink involved in this route
+ -"sources": all the sources than can be connected to the sink via vis route
