That is because we try to get this from cpufreq and cpufreq
has this info in kHz.

Not sure about this. I guess we can retain it the way it is as it is
something directly coming from hardware. CPU frequency in turn can come
cpufreq or acpi tables. ACPI table will reduce this further as it
always gives the info in MHz (on processors that has ACPI
based P-states support).
