Is there one clock controller at 0xea0000 of size 0x1000? We've
been trying to push people towards using the device model and
writing drivers with probe instead of using CLK_OF_DECLARE() for
their platform clocks. From the looks of this binding, we're
splitting up the different types of clocks into their own nodes
and then registering them with CLK_OF_DECLARE.
