rtl818x_pci: use generic power management
Earlier, drivers had to manage the device's power states, and related
operations, themselves. With the generic approach, these are done by PCI
core.
The only driver-specific jobs, .suspend() and .resume() doing were invoking
PCI helper functions pci_save/restore_state() and
pci_set_power_state(). This is not recommeneded as PCI core takes care of
that. Hence they became empty-body functions, thus define them NULL.
Compile-tested only.
