[U-Boot] [PATCH 04/07] Coldfire: M5271: Allow board header file to specify clock multiplier

[Richard Retanubun]

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.
