(origin/edac-amd-atl)

v2:
- Fix compilation error.
- Make remove_base_and_hole the inverse of add_base_and_hole.
- Move all map validation checks to validate_address_map at the
beginning of translation
v3:
- Fix bug where the legacy hole was not getting removed properly.
- Minor rework of functions for matching the normalized address and
logical cs fabric id.
v4:
- Merge common cases in map validation function.
- Fix map validation for cases that don't have explicit checks.
