The below patch added this quirk only for the first generation of family
15 processors, over time its noticed that its required for later
generations too.

"575203b4747c x86, MCE, AMD: Disable error thresholding bank 4 on some
models"

This patch extends the quirk to make it applicable till 7th Generation,
so as to address the below warning at boot:

"[Firmware Bug]: cpu 0, invalid threshold interrupt offset ..."
