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).
