hal: Clear VI feedback cal after VI capture path is started

When speaker protection is enabled, afe TX common calibration will be
pointing to VI feedback calibration. If any TX capture usecase is started
by passing HAL(tinycap), recording will fail.
Speaker protection module will set the afe tx common cal block to
handset mic once VI feedback path is started. This will ensure that
capture usecases can be supported with speaker protection enabled and
HAL by passed.

hal: update bt-sco sample rate before device enable

- Some BT solutions set sample rate only at the time of BT connection
  but not for every device switch. Due to this sample rate is not
  set properly after device switch.
- Update bt-sco sample rate before device enable instead of sample rate
  set parameters call.

audio: primary desc check for sonification

- Audio glitches on alarm expiry if alarm starts
  on screen lock/standby mode

- On alarm expiry alarm tone will start play on combo device
  &screen unlock tone try to play on headset which results
  multiple device switch, as a result audio glitches are audible

- Fix is to treat all non-music streams as sonification
  if sonfication strategy is used by primary desc which
  will avoid device switch

hal: start voip driver independent of voip output stream

- Voip driver requires voip output stream to be opened
to start itself. But it is possible that some applications
may use voip input and normal audio output. Code changes are
done to handle this scenario.
- It is possible that some applications may use different
sample rates for voip input and voip output streams. It is
handled now in such a way that, if the sample rate of the
secondly opening stream does not match with that of the
first one, the second stream will not be allowed to open
voice path for VoIP.

hal: Add new CSD API to reduce in call device switch delay

New CSD api is added to reduce device switch delay during voice call.
This api is called before enabling the devices so that csd voice call
sequence on MDM can run in parallel with device enable configuration
on APQ.

hal: fix listen and audio calibration concurency

- ACDB loader is maintaining the same calibration buffers
for both listen and audio. So there is a possibility that
the audio calibration buffers may be overwritten with listen
calibration soon after notifying the device busy state to
listen hal
- Avoid this issue by notifying listen hal before sending the
audio calibration so that listen hal can complete pushing its
calibration

hal: fix to handle voip issue when input stream starts first

- adev_open_output_stream() fails if the use case is already enabled.
Because of this, in case of VoIP, when the input stream is created
and started before creating Audio Track, then the output stream
creation fails.

- Fix this issue by giving exception for VoIP use case.

 Audio: Fix for audio loss on switching between speaker and USB headset

 - snd device reference count is not decremented when usb headset is
   unplugged, because touch tone is still active on usb headset.
   So when usb is plugged again device routing is not triggered as
   present and prev devices are same
 - Fix is to route audio to speaker as soon as usb headset is
   disconnected
