'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 value of speed passed into print_speed is in kHz, so divide speed by
1000 in the MHz else-if section to get MHz.
