I am not sure if it is no longer possible but at the time of addition of this
it was possible to build with CONFIG_COMMON_CLK=n and any error was reported[1]
I didn't want to add Kconfig dependency as this driver doesn't use any other
clock apis and this was added to meet some OPP(?) requirement IIRC. We can
drop the call to devm_of_clk_add_hw_provider if that is not the case. I need
to check it again as I can't recall all the details right now.
