As we're moving progressively towards the common clk API, which requires
the new clk_prepare/clk_unprepare calls, new code should be using the
dated API.  Please update this to do so (eg, by using clk_prepare_enable()
instead of clk_enable() for the simple solution.)  Better solutions
involve decoupling the two and only using clk_enable()/clk_disable() where
you really need the clock to be on.
