I also tried with "being able to do an alias" without success.
One idea could be to re-implement -c evaluation in frequency_info.c
BUT be aware that default switched:
  - with cpufrequtils cpufreq-info by default showed all cpus
  - with cpupower all read commands only show cpu 0 by default

  - with cpufrequtils cpufreq-set only sets the first cpu
  - with cpupower all write commands write to all cpus
and this is on purpose and should not change.
So unfortunately an alias won't be possible.
