EDAC/amd64: Remove module version string

The AMD64 EDAC module version information is not exposed through ABI
like MODULE_VERSION(). Instead it is printed during module init.

Version numbers can be confusing in cases where module updates are
partly backported resulting in a difference between upstream and
backported module versions.

Remove the AMD64 EDAC module version information to avoid user
confusion.
