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

stable inclusion
from stable-5.10.21
commit a03583775a5f3e0171e15692159cdbf7816ddf6f
bugzilla: 50609

--------------------------------

[ Upstream commit 6c13d7ff ]

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.
