audio: update audio volume table

Browse Source 
This patch Updates the volume_listener coverage to fix the low volume
index (volume key 1~10) can’t be mapped to volume listener index.  In
current setting, only stream volume larger than -8.6db will be applied
with volume listener tuning. This patch also updates Android volume
curve of SWB and VoIP.
