ASoC: msm: set the master gain to 0 on DSP while configuring

- Mute media volume and play any music clip then reboot
  the phone. Play music again noise comes. This noise
  is introduced in DSP/LPASS.

- DSP suggestion is to mute master volume gain while
  configuring ASM session to avoid such noise at
  begining of asm playback.

ASoC: msm: Fix for wma playback after SSR

After SSR apr session doesn't get destroyed as
the callback from apr driver doesn't come.Fix
this by not doing NULL allocation in q6asm callback.

ASoC: msm: qdsp6v2: clear old memhandle list when SSR happens

When SSR triggers, ASM gets RESET_EVENT callback.
Clear custom topology related old memhandle list here.
Otherwise for next ASM session opened after SSR,
old memhandle is sent to DSP and result in no audio.
Also, for ASM session while unmap during SSR, APR
command fail is expected, even then go ahead and
clear old mem handles relating to session.
Add changes to clear it from list.

[SCSI] async: introduce 'async_domain' type

This is in preparation for teaching async_synchronize_full() to sync all
pending async work, and not just on the async_running domain.  This
conversion is functionally equivalent, just embedding the existing list
in a new async_domain type.

The .registered attribute is used in a later patch to distinguish
between domains that want to be flushed by async_synchronize_full()
versus those that only expect async_synchronize_{full|cookie}_domain to
be used for flushing.

ASoC: Cold start latency reduction

This patch parallelizes FE (front end) and BE (back end)
when playback/capture path is set up. FE's and BE's which can
be parallelized should be indicated in corresponding machine file.
All the operations can be started asynchronously provided the usecase
supports asynchronous operation.
Parallelizing reduces the startup latency as both FE and BE opeations
run in parallel.

Repeat mode is not working in pcm offload path. When two streams
are used in a single session pcm format block should be sent
specific to each stream. Data sent on stream 2 is ignored by DSP
because pcm format block is always sent on stream 1. Fix is to
update pcm media format block to use correct stream id before
data is sent to DSP.

ASoC: compress: fix the target not going to TCXO shutdown

The error code propagated from the flush cmd in the trigger stop
is causing the error in the state of the soc compress framework.
This hinders in closing the BE connected to the FE.
If the AFE is not closed it prevents the target to go into TCXO
shutdown.
Fixed by removing the error handling of the flush command in the
trigger stop, since failure in flush doesn't signify the
failure in the stop command.
