I'll queue this up for 6.13.

There were previously two differences for server and non-server:
  * amd-pstate not enabled by default
  * amd-pstate cpufreq policy starting in performance mode vs power-save?

This series adjusts the first for at least the newer parts, but I would 
like to ask does it make sense to also evaluating changing the default 
policy to powersave as a follow up, or should this policy delta remain?
