ppc4xx: Merge PPC4xx DDR and DDR2 ECC handling
This patch merges the ECC handling (ECC parity byte writing) into one file (ecc.c) for all PPC4xx SDRAM controllers except for PPC440EPx/GRx. This exception is because only those PPC's use the completely different Denali SDRAM controller core. Previously we had two routines to generate/write the ECC parity bytes. With this patch we now only have one core function left. Tested on Kilauea (no ECC) and Katmai (with and without ECC).
