video: fbdev: skeletonfb: Convert to generic power management

PCI-specific power management (pci_driver.suspend and pci_driver.resume) is
deprecated.  If drivers implement power management, they should use the
generic power management framework, not the PCI-specific hooks.

Convert the sample code to use the generic power management framework.
