[U-Boot] [PATCH] powerpc/BSC9131RDB: Enable creation of dynamic partitions for NAND

[Ashish Kumar]

 * fdt_fixup_mtdparts is called from ft_board_setup
 * Run "mtdparts default" to create NAND partition on uboot
 * Use mtdparts to create partitions dynamically rather
    than using static partitions in device tree
