[PATCH v6 01/14] clk: Add clk_hw_get_clk() helper API to be used by clk providers

[Ritesh Harjani <riteshh-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

From: Rajendra Nayak <rnayak-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

Add a helper API that will allow clk providers to turn their clk_hw
structures into struct clk pointer.

Signed-off-by: Rajendra Nayak <rnayak-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
