cpupower: Restore format of frequency-info limit
The intel_pstate kselftest expects that the output of
`cpupower frequency-info -l | tail -1 | awk ' { print $1 } '`
to get frequency limits. This does not work after the following two
changes.
- 562e5f1a3: rework the "cpupower frequency-info" command
(Jacob Tanenbaum) removed parsable limit output
- ce512b840: Do not analyse offlined cpus
(Thomas Renninger) added newline to break limit parsing more
This change preserves human readable output if wanted as well as
parsable output for scripts/tests.
