crypto: atmel-sha - remove calls of clk_prepare() from atomic contexts

clk_prepare()/clk_unprepare() must not be called within atomic context.

This patch calls clk_prepare() once for all from atmel_sha_probe() and
clk_unprepare() from atmel_sha_remove().

Then calls of clk_prepare_enable()/clk_disable_unprepare() were replaced
by calls of clk_enable()/clk_disable().
