EDAC: introduce AMD Address Translation Library

JIRA: https://issues.redhat.com/browse/RHEL-26704

This patchset moves the ATL from amd64_edac into a different module so other
subsystems can make use of it.

v2: add a config in the (wrong) location to match what ark is doing
v3: rebased on top of latest
