cpupower: Print kernel and hardware frequency information
The kernel asserted frequency from scaling_cur_freq may not always match
the hardware reported frequency from cpuinfo_cur_freq.
Print both values when they are available, and only print the unavailable
message on x86 when the hardware frequency can't be read.
