The providers are all located in drivers/clk/ and hence no need
to export the clock operations to wider audience. Hide them by
moving to drivers/clk/clk-fractional-divider.h.

At least one user currently duplicates some functions that are provided
by fractional divider module. Let's export approximation algorithm and
replace the open-coded variant.
As a bonus the exported function will get better documentation in place.
