x86/MCE: Enable MCE broadcasting on new Centaur CPUs

Newer Centaur multi-core CPUs also support MCE broadcasting to all
cores. Add a Centaur-specific init function setting that up.

 [ bp:
   - make mce_centaur_feature_init() static
   - flip check to do the f/m/s first for better readability
   - touch up text
