ASoC: Intel: avs: Fixes and cleanups for 6.10

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Set of changes targeting the avs-driver only. No new features, patchset
either fixes or fortifies existing code.

Patchset starts off with a fix for debugbility on ICL+ platforms which I
have forgotten to fixup when providing support for these initially.
The next two address copier module initialization, most importantly,
silence the gcc 'field-spanning write' false-positive.

The following four:
6/13 ASoC: Intel: avs: Replace risky functions with safer variants
7/13 ASoC: Intel: avs: Fix potential integer overflow
8/13 ASoC: Intel: avs: Test result of avs_get_module_entry()
9/13 ASoC: Intel: avs: Remove dead code

address problems found out by Coverity static analysis tool.

The last two worth mentioning are: recommendation from the firmware team
to wake subsystem from D0ix when starting any pipeline -and- shielding
against invalid period/buffer sizes. Audio format shall be taken into
consideration when calculating either of these.
