ACPI: PM: Improve kerneldoc comments for suspend and hibernation functions

Browse Source 
This patch enhances the documentation for the ACPI power management

This includes the use of kernel-doc style comments which provide
developers with clearer guidance on the usage and expectations of
these functions.
