hal: limit AFE sample rate at 48Khz for non-44.1-support devices
After VoIP is closed, Music playback will resume. After
this behavior, DUT will crash after a period.
When VOIP entered standby, the VoIP use case is left to
mantain active state, then Music only can select VoIP
device. If VoIP device is handset, and sample rate of
playback is 44.1Khz, then AFE Sample Rate is configured
as 44.1Khz for handset. While COPP is set to 48Khz for
handset. This would cause sampling rate mismatch.
Limit AFE Sample Rate at 48Khz for non-44.1-support devices.
