You should be using SUNXI_CCU_GATE_DATA here

You're going to need a DT binding here too.

So we don't really want to expose all the clocks in the binding here, but only
the one that are going to be used by the devices (and not the "internal" ones),
so that will be usually the bus gates and the module gates.
If we need a PLL at some point, we can always export it, but that should be the
exception, not the default.
