Sorry, I think we're still waiting for the critical clocks stuff
to settle down so that Sunxi can use that instead of calling
clk_prepare_enable() in init code. For now, I've put the first
patch of the two into clk-next so that we can have proper orphan
tracking. Hopefully we resolve critical clocks soon so that we
can merge the defer part.
