Currently snd_soc_jack_report() always acquires codec->mutex and
synchronize DAPM widgets. This automation is helpful if jack has defined
widget. However if codec driver doesn't have defined jack widget and
non-jack widget wants to synchronize with report_sock_jack's thread which
is usually irq handler, it can make dead-lock as all DAPM widget
call-backs are called after codec->mutex acquisition.
Add new API snd_soc_jack_report_no_dapm() so codec driver can have ability
of control DAPM synchronization part of snd_soc_jack_report()

Previously, DSP used to setup the data path towards the
codec via slimbus. Now, the data path setup is broken into
two parts - one half of the path setup between apps to slimbus
and the other half from DSP. This configuration mode is
required to reduce overflow or underflow errors. Also this is
required to handle a configuration where mdm can talk
directly to codec.

Issue - backend dai prepare fails with concurrent LPA and non-LPA
sessions during stability tests. Since front end dai reference
count gets incremented for both sessions and backend dai hw_params
doesnt get invoked. This results NULL pointer in backend dai hw_params.
Fix - use the flag hwparam_set to ensure backend dai hw_parmas is
invoked properly.

Audio hardware path can be started not only for audio playback/capture
but also voice call. ADM COPP is created through Q6ADM driver
when AFE port is started. For voice call use case, creating
ADM COPP in DSP wastes unnecessary memory resource. To create
ADM COPP only for audio playback/capture case, management logic
is moved to pcm routing driver which has information about session
ID of MultiMedia streams and state of audio back-ends. With this
information, pcm routing driver decides to start/stop ADM COPP.
