The .suspend() and .resume() callbacks are not defined for this driver.
Still, their power managemgement stucture can be easily upgraded to
gemeric, without affecting its normal behaviour.

Hence, define them NULL and use struct dev_pm_ops type to bind them.

Compile-tested only.

Same question as for 2/6.
