ACPI / PM: Do not execute legacy driver PM callbacks
Since all ACPI drivers in the tree should have been switched to power management handling based on struct dev_pm_ops, modify the ACPI bus type driver so that is doesn't execute legacy driver power management callbacks from the functions pointed to by the members of the acpi_bus_pm structure.
