As ppc4xx currently only supports the deprecated nand_spl infrastructure and nobody seems to have time / resources to port this over to the newer SPL infrastructure, lets remove NAND booting completely. This should not affect the "normal", non NAND-booting ppc4xx platforms that are currently supported.
