[ Upstream commit 2734fdbc9b ]
When we are successful in using cpufreq min/max limits,
skip setting the raw MSR limits entirely.
This is necessary to avoid undoing any modification that
the cpufreq driver makes to our sysfs request.
eg. intel_pstate may take our request for a limit
that is valid according to HWP.CAP.MIN/MAX and clip
it to be within the range available in PLATFORM_INFO.
