ehci/ohci just define .suspend/.resume functions for dev_pm_ops, but in order to support both STR(suspend-to-ram) and hibernation, other callbacks such as .freeze/.thaw are also required. Registering all required callbacks for both STR and hibernation can be done by SIMPLE_DEV_PM_OPS macro function.
