assigned-clocks and assigned-clock-parents are not a *required* property,
as that depends on a number of things and someone *may* want to omit it.
Besides, that's related to how the drivers interact with / setup the hardware
and not with the hardware itself... you can keep the assigned-clocks and
assigned-clock-parents in your examples, but again they're definitely not
required properties.
