EDAC/amd64: Add new register offset support and related changes

Introduce a "family flags" bitmask that can be used to indicate any
special behavior needed on a per-family basis.

Add a flag to indicate a system uses the new register offsets introduced
with Family 19h Model 10h.

Use this flag to account for register offset changes, a new bitfield
indicating DDR5 use on a memory controller, and to set the proper number
of chip select masks.

Rework f17_addr_mask_to_cs_size() to properly handle the change in chip
select masks. And update code comments to reflect the updated Chip
Select, DIMM, and Mask relationships.
