Add a new method to the PCI bridge interface, PCIB_POWER_FOR_SLEEP(). This
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.
