[PATCH v2] ASoC: da7219: scope AAD suspend and resume helpers to CONFIG_PM

[Pengpeng Hou]

In current linux.git, da7219_aad_suspend() and
da7219_aad_resume() are defined and declared unconditionally. However,
their only in-tree callers are the component PM callbacks in da7219.c,
which are already guarded by #ifdef CONFIG_PM.

This inconsistency leads to unnecessary code inclusion and potential
compiler warnings when CONFIG_PM is disabled. Match the helper
declarations and definitions to the callers' scope and provide no-op
!CONFIG_PM stubs in the header.

Hi Mark, 
I have rebased this patch against the current tree. The previous version 
failed to apply likely due to context shifts in the AAD header/source file.

Changes in v2:
- Rebased on top of the latest tree to fix application failure.
- No functional changes from v1.
