I assume you are referring to the use in mtk_find_parent_rate() and
a few of the mtk_common_clk_*_init() functions.

FYI, I would like to get away from that usage eventually. It seems
pretty fragile. And now you've give another reason to motivate that
change as well. I have so many other MediaTek clock refactor patches
that I'm juggling right now, it will take a while to get around to it
though.

As it happens, mtk_clk_vlpckgen is actually globally unique, so I will
just keep it to be consistent for now and work towards unique naming
for all of the MediaTek clocks later.
