[PATCH v1 2/3] ACPI: PM: s2idle: Staticise LPS0 callback functions

["Rafael J. Wysocki" <rafael@kernel.org>]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The LPS0 callback functions in x86/s2idle.c can be made static, so do
that and remove their declarations from sleep.h.

While at it, add the _lps0 suffix to their names to indicate that
they are LPS0-specific.

No functional impact.
