Viresh Kumar 270b9f421e SPEAr: clk: Add Fractional Synthesizer clock 
All SPEAr SoC's contain Fractional Synthesizers. Their Fout is derived from
following equations:

Fout = Fin / (2 * div) (division factor)
div is 17 bits:-
     0-13 (fractional part)
     14-16 (integer part)
     div is (16-14 bits).(13-0 bits) (in binary)

     Fout = Fin/(2 * div)
     Fout = ((Fin / 10000)/(2 * div)) * 10000
     Fout = (2^14 * (Fin / 10000)/(2^14 * (2 * div))) * 10000
     Fout = (((Fin / 10000) << 14)/(2 * (div << 14))) * 10000

div << 14 is simply 17 bit value written at register.

This patch adds in support for this type of clock.
