method is used by the PCI bus driver to query the power management system to determine the proper device state to be used for a device during suspend and resume. For the ACPI PCI bridge drivers this calls acpi_device_pwr_for_sleep(). This removes ACPI-specific knowledge from the PCI and PCI-PCI bridge drivers. Reviewed by: jkim
