ACPI: Get the device power state in the course of scanning device
Get the device power state in the course of scanning device if the device
power flag is power_managable. i.e. The device has the _PSx/_PRx object.
At the same time before the drivers/acpi/power module is loaded, there is no
relation between acpi_power_resource and acpi device. So the first parameter
of acpi_power_get_state is changed to acpi_handle.
