starfire: use generic power management
With legacy PM, drivers themselves were responsible for managing the device's power states and takes care of register states. After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations. Thus, there is no need to call the PCI helper functions like pci_save/restore_sate() and pci_set_power_state(). Compile-tested only.
