ppc4xx: Fix problem with SDRAM init in bamboo NAND booting port

This patch fixes a problem spotted by Eugene O'Brian (thanks Eugene)
introduced by the commit:

ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.S

With this patch SDRAM will get initialized again and booting from NAND
is working again.
