Consider the below scenario, When ACP and SoundWire managers are in
D3 state and SoundWire manager power off mode is selected and acp and
SoundWire manager instances are in runtime suspended state.
In this case, for the ACP PME wake event, the ACP PCI driver should resume
SoundWire manager devices based on wake enable status set.
Add code for handling ACP PME wake event for runtime suspend scenario
when SoundWire power off mode is selected.

The earlier acp_reset flag is set to true in two instances as mentioned
below.
1. When active SoundWire manager instances power mode is set to
Power off mode when SoundWire configuration is selected.
2. For other acp configurations
As code being refactored and common function being used for scanning
SoundWire controller, acp_reset flag update logic is dropped.
Instead of it, check the SoundWire manager instance enable state, based on
it update sdw_en_stat flag which will be used to apply ACP init/de-init
sequence during suspend/resume callbacks based on flag set value when
SoundWire configuration is selected.
For other acp configurations, acp init/de-init will be called by default.
Refactor existing pm ops logic for SoundWire configuration and use
sdw_en_stat flag for invoking acp init/de-init sequence.

The compile warning with -Wformat-truncation at
sdw_amd_scan_controller() is false-positive; the max loop size is
AMD_SDW_MAX_MANAGERS (= 2), hence it fits with the given size.
For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.

On Pink Sardine machines that don't have SdW controllers in use, the property
`mipi-sdw-manager-list` won't exist. There is no point in showing an error
to a user when this situation is encountered.
Furthermore if the machine doesn't have a DMIC connected to the ACP, there
may be no platform devices created either.
Downgrade the associated message to debug.

AMD SoundWire manager supports different power modes.
acp_reset flag will be set to false only when SoundWire manager power
mode is selected as ClockStop Mode. For rest of the combinations
(ACP PDM + SDW), acp_reset flag will be set to true.
When acp_reset flag is set, acp de-init and acp init sequence should
be invoked during suspend/resume callbacks.

In PDM config case, ACP PCI driver retrieves dev index from
