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

[Pengpeng Hou]

From: pengpeng.hou@xxxxxxxxxxxxxxxx

In current linux.git (1954c4f01220), 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.
