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.
