Richard Retanubun e0db344fab Coldfire: M5271: Allow board header file to specify clock multiplier 
M5271 dynamic clock multiplier. It is currently fixed at 100MHz.

Allow the board header file to set their own multiplier and divider.
Added the #define for the multiplier and divider to the cpu header file.
