[PATCH] amd64_edac - Add Family 17h Model 70h PCI IDs

Dear Mr. Petkov,

I noticed the current EDAC driver doesn't support the new Zen 2 (model 70h) processors, so I patched the new device ids in. The changes are minimal, I merely extended the existing enums with information from the new models.

This is my first kernel patch and I'm not sure I followed the guide (kernel.org/doc/html/v5.2/process/submitting-patches.html) correctly, so please let me know if I need to resubmit this email with updated formatting prior to review.

Sincerely,
Isaac Vaughn
