PM / Runtime: Correct documented return values for generic PM callbacks
As of commit 05aa55dddb9ee4045c320661068bea78dad6a6e5 ("PM / Runtime: Lenient generic runtime pm callbacks"), the generic power management callbacks pm_generic_runtime_suspend() and pm_generic_runtime_resume() return 0, not -EINVAL, if the device doesn't provide its own callbacks.
