[PATCH] clk: s2mps11: Use kcalloc instead of kzalloc for array allocation

[PATCH] clk: s2mps11: Use kcalloc instead of kzalloc for array allocation

[Vaibhav Hiremath]

This patch cleans up the driver for,

  - Use devm_kcalloc varient 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.

Since I do not have platform to test, it would be helpful if someone
tests it for me.
I have build tested it.
