Merge tag 'amd-pstate-v6.13-2024-10-29' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/superm1/linux

Merge amd-pstate driver updates for 6.13 from Mario Limonciello:

"Update the amd-pstate driver to set the initial scaling frequency policy
 lower bound to be lowest non-linear frequency. This will have a slight
 power consumption impact but should lead to increased efficiency.

 Also amd-pstate is enabled by default on servers starting with newer
 AMD Epyc processors.

 Align more codepaths between shared memory and MSR designs.

 Add various code cleanups to rename functions and remove redundant calls."
