'cpupower frequency-info -ln' returns kHz values on systems with MHz range
minimum CPU frequency range.  For example, on a 800MHz to 4.20GHz system
the command returns

hardware limits: 800000 MHz - 4.200000 GHz

The code that causes this error can be removed.  The next else if clause
will handle the output correctly such that

hardware limits: 800.000 MHz - 4.200000 GHz

is displayed correctly.

[v2]: Remove two lines instead of fixing broken code.
