ACPI / PM: Add function for device power state initialization
Add function acpi_bus_init_power() for getting the initial power state of an ACPI device and reference counting its power resources as appropriate. Make acpi_bus_get_power_flags() use the new function instead of acpi_bus_get_power() that updates device->power.state without reference counting the device's power resources. Signed-off-by: Rafael J.
