EDAC/amd64: Do not load on family 0x15, model 0x13

Browse Source 
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.
