On most Freescale 85xx boards, the CONFIG_SYS_CLK_FREQ and CONFIG_DDR_CLK_FREQ macros are defined like this:
This means that in order to use these macros, the callers must have prototypes for the corresponding functions. On 85xx, only speed.c uses these macros, so let's define the prototypes there. This eliminates the need to define the prototypes in the board config files.

I'm posting the patch for review, and if everyone likes it, inclusion in the 85xx repo. Comments welcome.
