clk: clocking-wizard: calculate dividers fractional parts

Browse source

Calculate dividers fractional parts to optimally modulate output frequency.
Clocking wizard supports having multiplier m and divisors d and o.
Currently the fractional parts of m and o are not utilised.
For the pixel clock usecases a higher accuracy is needed..
Adding support for m and o to have fractional values.
