ACPI / PM: Allow attach/detach routines to change device power states
Make it possible to ask the routines used for adding/removing devices to/from the general ACPI PM domain, acpi_dev_pm_attach() and acpi_dev_pm_detach(), respectively, to change the power states of devices so that they are put into the full-power state automatically by acpi_dev_pm_attach() and into the lowest-power state available automatically by acpi_dev_pm_detach().
