[PATCH 1/6] powerpc: Add prototypes to header file

[Sascha Hauer]

This adds prototypes of the board specific functions
fsl_ddr_board_options() and fsl_ddr_board_info() to a header
file. Including this header file from the board files reveals
that the prototypes are different across the different implementations,
so harmonize them.
