Subject: [PATCH] selftests: cpufreq: conform test to TAP
This test outputs lots of information. Let's conform the core part of
the test to TAP and leave the information printing messages for now.
Include ktap_helpers.sh to print conformed logs. Use KSFT_* macros to
return the correct exit code for the kselftest framework and CIs to
understand the exit status.
