x86/cpu/amd: Set __max_die_per_package on AMD

commit 76e2fc63ca40977af893b724b00cc2f8e9ce47a4 upstream.

Set the maximum DIE per package variable on AMD using the
NodesPerProcessor topology value. This will be used by RAPL, among
others, to determine the maximum number of DIEs on the system in order
to do per-DIE manipulations.

 [ bp: Productize into a proper patch. ]
