PPC4xx: Denali core: Fix incorrect DDR row bits
The SPD detection code for the Denali memory controller used on some ppc4xx processors incorrectly encodes DDR0_42. With certain memory configurations, this can cause the bootwrapper to incorrectly calculate the installed memory size, because the number of row bits is wrong. This patch fixes that encoding.
