mb/pcengines/apu2/OemCustomize.c: make AGESA AmdInitPost happy
Bank interleaving does not work on this platform, disable it.
Additionally enable ECC feature on SKUs supporting it. AmdIntPost
returns success thanks to these settings.
TEST=boot apu2 4GB ECC and apu3 2GB no ECC and see AGESA_SUCCESS after
AmdInitPost
