[PATCH v3 02/15] cpufreq/amd-pstate: Use boost numerator for upper bound of frequencies

[Mario Limonciello <mario.limonciello@amd.com>]

commit 18d9b5227121 ("cpufreq/amd-pstate: Use nominal perf for limits
when boost is disabled") introduced different semantics for min/max limits
based upon whether the user turned off boost from sysfs.

This however is not necessary when the highest perf value is the boost
numerator.
