drivers/rtc/rtc-coh901331.c: use clk_prepare_enable() and clk_disable_unprepare()
clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
clk_enable, and clk_disable and clk_unprepare. They make the code more
concise, and ensure that clk_unprepare is called when clk_enable fails.
A simplified version of the semantic patch that introduces calls to these
functions is as follows: (http://coccinelle.lip6.fr/)
// <smpl>

expression e;
@@
- clk_prepare(e);
- clk_enable(e);
+ clk_prepare_enable(e);

expression e;
@@
- clk_disable(e);
- clk_unprepare(e);
+ clk_disable_unprepare(e);
