Increase the maximum ports in APR. Some Apps may support
multiple clients which exceeds the number of clients
supported in APR. This change increases number of ports
used in APR upto 8 sessions.

ASoC: msm: Do not deregister APR mmap handle for ASM Custom Topology

Remove APR deregister call from ASM Custom Topology to
ensure that the RESET event is called during SSR to
signal that ASM custom topology needs to be sent.

Various error handling is also added so that reference
count for apr deregister and register also happens properly.

ASoC: wcd9xxx: Update button release thresholds based on current micbias

During short button press, the button release threshold
registers are updated based on the determined button number
so that when mic voltage goes above the programmed value,
release interrupt will be triggered. This reduces delay in
reporting button release. However, the release thresholds
should be programmed based on the current micbias voltage
instead of programming based on 2.7V micbias. Otherwise,
it is possible that during playback where micbias is switched
to VDDIO (1.8V), the mic voltage would never go beyond the
voltage programmed in release threshold registers there by
not generating release interrupt at all.

ASoC: wcd9xxx: Avoid enabling button polling from event notify handler

During insertion, it is possible that recording is already
enabled from handset which will switch to headset. During
POST_MICBIAS_2_ON event, though button polling is not actually
enabled, due to polling_active becomes true, the event
notification handler pauses and re-starts button polling.
This could lead to unknown state for button polling state
machine.

ASoC: msm: Reset the stream open flag after CMD_CLOSE is sent to DSP

In case of gapless playback, driver does not wait for EOS. CMD_CLOSE
for stream one or two can be called from compress driver free before
EOS ACK for stream one is received. This can result in CMD_CLOSE to
be sent for already closed stream. Reset the stream open flag after
CMD_CLOSE is sent to DSP to prevent multiple CMD_CLOSE on same
stream.
