video: fbdev: cirrusfb: Remove useless reference to PCI power management

PCI-specific power management (pci_driver.suspend and pci_driver.resume) is
deprecated.  The cirrusfb driver has never implemented power management at
all, but if it ever does, it should use the generic power management
framework, not the PCI-specific hooks.

Remove the commented-out references to the PCI-specific power management
hooks.
