Subject: [PATCH 0/8] cpufreq: Auto-register with energy model

Provide a cpufreq driver flag so drivers can ask the cpufreq core to register
with the EM core on their behalf. This allows us to get rid of duplicated code
in the drivers and fix the unregistration part as well, which none of the
drivers have done until now.

This would also make the registration with EM core to happen only after policy
is fully initialized, and the EM core can do other stuff from in there, like
marking frequencies as inefficient (WIP). Though this patchset is useful without
that work being done and should be merged nevertheless.

This doesn't update scmi cpufreq driver for now as it is a special case and need
to be handled differently. Though we can make it work with this if required.

This is build/boot tested by the bot for a couple of boards.
