Ok, I'll move the fixed factor clocks out of the ccu_common list.

I tried my best already to move the common code, but it's not clear at
this point what can be factorised and what will only be used by a
single clock driver. Obviously, as we will support more SoCs, that
will become clearer and we will be able to factor out the code that
needs to be.

Ack, consider it done.

Thanks!
