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.
