ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSS

BugLink: https://bugs.launchpad.net/bugs/1863019
[ Upstream commit c95b7595f85c688d5c569ddbbd6ab6a4bdae2f36 ]

In general, it is not correct to call pm_generic_suspend(),
pm_generic_suspend_late() and pm_generic_suspend_noirq() during the
hibernation's "poweroff" transition, because device drivers may
provide special callbacks to be invoked then and the wrappers in
question cause system suspend callbacks to be run.  Unfortunately,
that happens in the ACPI PM domain and ACPI LPSS.

To address this potential issue, introduce "poweroff" callbacks
for the ACPI PM and LPSS that will use pm_generic_poweroff(),
pm_generic_poweroff_late() and pm_generic_poweroff_noirq() as
appropriate.
