Introduce a common infrastructure for sharing clock initialization between
SoCs.

Does this need range-checking? Or do we assume that since this is an
internal function, "clk_id" will never be out-of-range?

That was my assumption indeed. I could add a range check if you think that's
useful.

It's probably OK if it's a purely internal function; I just wanted to
double-check.
