agp/efficeon: Convert to generic power management
Convert agpgart-efficeon from legacy PCI power management to the generic power management framework. Previously agpgart-efficeon used legacy PCI power management, which means agp_efficeon_suspend() and agp_efficeon_resume() were responsible for both device-specific things and generic PCI things like saving and restoring config space and managing power state. In this case, agp_efficeon_suspend() was empty, and agp_efficeon_resume() already did only device-specific things, so simply convert it to take a struct device * instead of a struct pci_dev *. Based on 0aeddbd0cb07 ("via-agp: convert to generic power management") by Vaibhav Gupta <vaibhavgupta40@gmail.com>.
