arm64: kernel: Add cpufeature 'enable' callback
commit 1c0763037f1e1caef739e36e09c6d41ed7b61b2d upstream.
This patch adds an 'enable()' callback to cpu capability/feature
detection, allowing features that require some setup or configuration
to get this opportunity once the feature has been detected.
