perf/x86/intel/uncore: Clean up hardware on exit

When tearing down the boxes nothing undoes the hardware state which was setup
by box->init_box(). Add a box->exit_box() callback and implement it for the
uncores which have an init_box() callback.

This misses the cleanup in the error exit pathes, but I cannot be bothered to
implement it before cleaning up the rest of the driver, which makes that task
way simpler.
