description:
Normalize some machine dependent CPU frequenct sysctl variables.
This moves machdep.*.frequency.* to machdep.cpu.frequency.*.
This was proposed on tech-kern some time ago. The intention is to allow
third-party tools such as estd and conky to more easily and reliably
fetch or modify the current CPU frequency without iterating through
various machine-dependent variables to check their presence.
