crypto: picoxcell - Update to the current clk API
The picoXcell hardware crypto accelerator driver was using an older version of the clk framework, and not (un)preparing the clock before enabling/disabling it. This change uses the handy clk_prepare_enable function to interact with the current clk framework correctly.
