The logic in clk_get_by_index() may be useful for other properties than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents' follows the same model.
This commit refactors clk_get_by_index() by introducing an internal function clk_get_by_indexed_prop() that allows to specify the name of the property to process. The original clk_get_by_index() call is simply directed through this helper function with the property name fixed to "clocks".
