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.
