amplifier: add set_parameters method
- audio hal should pass the audio_device parameters to the amplifier
to allow the amplifier to make decisions based on the additional
parameters. For example, we may want to change settings for DTS
TrueMedia use case.

audio_amplifier: add hooks for stream parameter manipulation
This allows to modify audio parameters before the first
device selection happens which is necessary when setting ANC parameter
since it must happen before audio hal hits voice_start_call() and
selects devices. If setting ANC after stream has been started it will
trigger a re-selection of devices and cause a short downtime.

* Compiled as apart of vendor-snapshot, so need to
make sure it compiles.

audio_amplifier: Add hook for amplifier calibration
Sometimes the amplifier will need to do calibration and fw download
on the very first boot. For example, it will need to load calibration
files from another partition, download calibration firmware to the
amplifier and play silence sound for some seconds.
While the current interface, amp_module_open, is able to handle most
of the operations mentioned above, it is not able to allow the HAL
to play silence sound, because it cannot get the needed audio_device,
or adev, it is not able to enable the snd device, and write silence
pcm data using pcm_write interface.
This change adds an interface to allow the audio_amplifier HAL to
calibrate the amplifier. It passes the required audio_device struct
to audio_amplifier as a parameter, and is called after opening the
audio_amplifier module.
