Probably, it can be rephrased as "Providing struct dev_pm_ops, this
patch enables to save and restore register values for hibernation".
Anyway, implementing such features also resulted in proper behavior
with runtime-pm enabled kernel. (Before this patch, there were issues
with sleep-wakeup with lp3974 irqs if runtime-pm is enabled)
