PM: runtime: add devm_pm_clk_create helper
A typical code pattern for pm_clk_create() call is to call it in the
_probe function and to call pm_clk_destroy() both from _probe error path
and from _remove function. For some drivers the whole remove function
would consist of the call to pm_remove_disable().
Add helper function to replace this bolierplate piece of code. Calling
devm_pm_clk_create() removes the need for calling pm_clk_destroy() both
in the probe()'s error path and in the remove() function.
