Subject: [Suggested-by:Shuah Khan Patch 1/1] cpufreq: amd-pstate: Add explanation for X86_AMD_PSTATE_UT
This kernel module is used for testing. It's safe to say M here.
It can be modprobed even without amd-pstate module.
When the comparison test is performed, it can load other module
like acpi-cpufreq to test cases, then compare the test results.
When only the test for amd-pstate is performed, it can tell the
users they loaded a wrong module like acpi-cpufreq.
