Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver has not defined .resume(), hence define it as NULL.
Change function parameter in both .suspend() to "struct device*" type and
mark the parameter as "__attribute__((unused)) " as the function body is
empty.
Compile-tested only.
