[PATCH 4/5] clk: Add flag to prevent frequency changes when walking subtrees

Can you be more specific? What function from the API is supposed to do
what I need? AFAIU, none of them is properly locking the rate during a
subtree walk, but if I misread one of them, I'd be glad to drop all this.

Thanks,
Miquèl
