> The MediaTek clock driver currently have two ways to indicate the parent
> tree that contains the parent clock. This adds to code complexity and
> makes it more difficult to know the "right thing" to do in new drivers.
>
> The plan here is to convert all mux clocks to use the more robust option
> of using struct mtk_parent to specify parent clocks.
>
> The conversion to the static const struct mtk_parent arrays was done
> by script to minimize the chance of error (and save time).
>
> After the conversion, we can drop two of the clock flags that are no
> longer used and remove the dead code.
