[ 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.
