interfaces/{cpu,power}-control: add more accesses for commercial devi…

…ce tuning

Merge pull request #11404 from anonymouse64/feature/optimization-script-accesses

See the init_post_boot.sh[1] script for a summary of these accesses. There are
other accesses we are still evaluating where to provide them, they likely
belong in either custom-devices or in system-files for specific devices
however.

See also salesforce ticket 00320679.
