cpufreq: Add defensive check during driver registration
Currently, cpufreq allows drivers to implement both ->target() and
->target_index() callbacks, but that can lead to ambiguous or incorrect
behavior.
For this reason, prevent cpufreq drivers implementing both ->target()
and ->target_index() at the same time from registering.
This check can help to catch driver implementation mistakes early and
improve overall robustness, without affecting existing valid drivers.
