I2S_CYA register is a spare register reserved for any issue
in design. I2S4 has "i2s4a" and "i2s4b" pins in the pinmux.
In order to select i2s4b pin for I2S4 instance, we need to
enable CYA register

Set default register values for AHUB modules in regmap. This will
ensure after runtime suspend/resume AHUB register POR values
does not get reset to 0.

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.

I2S MBIST comes up in random state and therefore
SLCG needs to be toggled OFF and ON before the I2S
controller can be used normally.
This patch implements WAR in response to SLCG notifier.
- Set I2S controller in master mode.
- toggled I2S SLCG OFF and ON.
