EDAC/amd64: Do not load on family 0x15, model 0x13
Those were only laptops and are very very unlikely to have ECC memory.
Currently, when the driver attempts to load, it issues:
EDAC amd64: Error: F1 not found: device 0x1601 (broken BIOS?)
because the PCI device is the wrong one (it uses the F15h default one).
So do not load the driver on them as that is pointless.
