   cpufreq/amd-pstate-ut: Add test case for mode switches (2024-09-09 
10:26:26 -0500)

----------------------------------------------------------------
second round of amd-pstate changes for 6.12:

* Move the calculation of the AMD boost numerator outside of
   amd-pstate, correcting acpi-cpufreq on systems with preferred cores
* Harden preferred core detection to avoid potential false positives
* Add extra unit test coverage for mode state machine
