ppc4xx: Remove 4xx NAND booting support
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.
