df71a05324 amd64_edac: Enable driver on F15h
Add the PCI device ids required for driver registration. Remove
pvt->ctl_name and use the family descriptor directly, instead. Then,
bump driver version and fixup its format. Finally, enable DRAM ECC
decoding on F15h.

bcd781f46a amd64_edac: Cleanup NBSH cruft
Remove reporting of errors with UC bit set - this is done by the MCE
decoding code anyway and this driver deals with DRAM ECC errors only. UC
(NB uncorrectable error) doesn't necessarily mean it is a DRAM error.
Remove unused macros while at it.

6d5db46687 EDAC, MCE: Fix NB error formatting
Minor formatting fixup since the information which core was associated
with the MCE is not always valid.

Building for X86_32 produces shift count warnings, so use BIT_64() to
eliminate the warnings.
