ehci/ohci-platform 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.
