ACPI: Get the device power state in the course of scanning device

Browse source

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.
