[PATCH v2 01/22] EDAC/amd64: Don't set up EDAC PCI control on Family 17h+

[Yazen Ghannam]

EDAC PCI control is used to detect/report legacy PCI errors like
"Parity" and "SERROR". Modern AMD systems use PCIe Advanced Error
Reporting (AER), and legacy PCI errors should not be reported.

Remove EDAC PCI control setup on AMD Family 17h and later systems.
