PM: Introduce pm_power_off_prepare
Introduce the pm_power_off_prepare() callback that can be registered by the interested platforms in analogy with pm_idle() and pm_power_off(), used for preparing the system to power off (needed by ACPI). This allows us to drop acpi_sysclass and device_acpi that are only defined in order to register the ACPI power off preparation callback, which is needed by pm_power_off() registered in a much different way.
