Volume reset for alsabat testing (#1010)

* lib.sh: rename function reset_PGA_volume to a more generic name

the volume ctl name PGA is for IPC3, IPC4 uses keyword gain.
so rename the function to a more generic name to cover IPC4.

* lib.sh: add IPC4 gain volume ctl support in volume reset function

No all IPC4 gain controls can set 0dB directly, maybe there're
some problems there. As the alternative, use 100% for IPC4 gain.
Will be unified after the problem is fixed.

* lib.sh: reset all sof volume to 0dB before alsabat testing

We have aligned that to use 0dB for all sof volume controls in CI test.
