Below are the hypothetical scenarios
- Drivers are in suspend state while reboot and PCM Open call from
userspace is received after driver shutdown [APE is power gated
already]
- PM domain handling doesn't ensure proper functionality after driver
shutdown is called
The change handles with the below fix
- ALSA PCM Open API first executes runtime resume of each driver.
So need to prevent any reg access in runtime resume of drivers.
- ALSA PCM Open executes ADMAIF startup after runtime resume of
each driver. If ADMAIF startup returns failure based on shutdown,
PCM Open operation will fail, this will break PCM Open path and
will ensure no further ALSA APIs/Callbacks are called.

Certain usecase requires different audio and client channels settings
inside ahub, so this needs to be handled with dedicated Channels mixer
control for each module.
This change will introduce channels mixer control and cif controls to
admaif,dmic,i2s and all other internal module is control with a single
channel control.
-Support mono channel SFC
-Support mono channel Mixer
-Cleanup drivers

Set idle_bias_off for all t210 xbar modules to ensure module runtime
suspend/resume works when module is idle.
Ensure regcache is synced back to hardware during runtime resume so
that register content does not get lost if it is written during
runtime suspend state.
Add suspend APIs for all module to mark regcache dirty while device
goes into suspend to ensure register values does not get lost across
system suspend/resume.

Instead of using duplicate clock of "d_audio" for all AHUB modules
get/put runtime pm reference of the parent module from runtime_pm
suspend/resume routine of all AHUB modules. This will ensure AHUB
xbar is up before other drivers tries to access any register. Also
it will ensure both d_audio and APE clocks are enabled when needed.

When using RBTREE cache, there can be allocations the first time
a register is accessed. This can cause an attempt to schedule while
atomic in the case that the regmap is using a spinlock. This can be
resolved by using a flat cache.
