ACPI / x86: Add support for LPS0 callback handler

[ Upstream commit 20e1d6402a71dba7ad2b81f332a3c14c7d3b939b ]

Currenty the latest thing run during a suspend to idle attempt is
the LPS0 `prepare_late` callback and the earliest thing is the
`resume_early` callback.

There is a desire for the `amd-pmc` driver to suspend later in the
suspend process (ideally the very last thing), so create a callback
that it or any other driver can hook into to do this.
