I don't have a strong opinion on whether we need a Kconfig prompt
or not. Protection Keys has relatively little code associated
with it, and it is not a heavyweight feature to keep enabled.
However, I can imagine that folks would still appreciate being
able to disable it.
We will hide the prompt for now.
