clk: s2mps11: Use kcalloc instead of kzalloc for array allocation
This patch cleans up the driver for, - Use devm_kcalloc() variant instead of devm_kzalloc() for array allocation. - clk_prepare()/unprepare(), remove "ret" variable as it is not required - use __exit for cleanup function As I am referring this driver as a reference for my 88pm800 clk driver, applying same changes here as well.
