When BUSID pin is connected to ground, wsa speaker should be
set as left. When it is connected to VDD, wsa speaker should
be set as right. Current setting is inversed.
Correct stereo wsa speaker left/right setting for 8976.

In device switch from bongo speaker to HPH, observe
pop in headset. Since the PA select bit is changed
to HPH before DAC disable when tearing down bongo
speaker, this can result in pop in headset. Move
the PA selection bit to be changed to HPH after
PA and DAC disable.

After SSR, MICBIAS is not enabled as micb_ref is not correct.
So set micb_ref to zero post SSR.

From second detection onwards, buffered data has one extra
stale sample before the actual data even though CPE TX PP
(PingPong) buffer is properly disabled. Avoid this extra data
by clearing TX PP buffer memory after reading the complete buffer.

When userspace requests small duration of buffer then it is possible
that the buffer can overflow if only one buffer is queued at a time.
This is because of more channel setup time than buffer size duration.
Queue two buffers with slimbus before starting AFE port to avoid
data loss.

Issue slim slave port disconnect command to tear
down the audio playback path and then wait for
the channel removal interrupt from the slimbus slave.
This is required because of the slim protocol (pull
mode) being used for 44.1KHz native audio playback.
If MSM side slimbus channels are closed first followed
by slim slave ports, it will lead to underflow errors
at the end of audio playback with 44.1KHz sample rate.
To avoid underflow errors, slim slave port disconnect
command is issued explicitly.
