Yazen Ghannam 99328b4b44 x86/cpu/amd: Set __max_die_per_package on AMD 
commit 76e2fc63ca 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. ]

Fixes: 028c221ed1 ("x86/CPU/AMD: Save AMD NodeId as cpu_die_id")
