In most of the cases partitions info, width, etc comes from board files. And
device structure may be defined in machine files, common to all board files.
Thus, we need to set platform data from board file, for which
fsmc_nand_set_plat_data routine is required.

This routine will be used in SPEAr fsmc patches which are sent in a different
patchset.
