Considering the more prevalent usage of CLK_OF_DECLARE() in drivers/clk
led me into thinking it was the normal way for the clock drivers.
Keeping only one clock driver using a different approach looked odd to
me. Anyways, I don't have any other reason to pursue this case.

Sure. There are still some valid cleanups even if we plan to retain the
platform driver infrastructure. I will split and repost.
