[U-Boot] [U-Boot, v2, 2/5] clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()

[Philipp Tomsich]

> 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".
