[U-Boot] [PATCH] mpc85xx: add function prototypes for sys and ddr clocks to speed.c

[Timur Tabi <timur@freescale.com>]

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.
