Some platforms allow for clock gating and control of bus interface unit clock

and ciu clocks for clock gating and clock speed determination.
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.
