ACPI: Introduce acpi_bus_power_manageable function
Introduce function acpi_bus_power_manageable() allowing other (dependent) subsystems to check if ACPI is able to power manage given device. This may be useful, for example, for PCI device power management. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
