cpufreq/amd-pstate-ut: Fix amd_pstate_ut_check_freq failure with 'Requested CPU Min frequency' BIOS option
Since commit 608a76b65288 ("cpufreq/amd-pstate: Add support for the
"Requested CPU Min frequency" BIOS option"), amd-pstate driver sets
policy->min to frequency corresponding to bios_min_perf if a valid BIOS
programmed min frequency value is detected.
amd_pstate_ut_check_freq expects policy->min to always match
lowest_nonlinear_freq which does not hold true on platforms with user
configured BIOS min freq.
Update the test case to compare policy->min to bios_min_freq on
platforms that set it. Final comparison is adjusted to account for
insane values by clamping the result within the supported frequency
range.
While at it, move freq_to_perf() and perf_to_freq() helpers to internal
header to allow their use from amd-pstate-ut.
