lockdep: Enable PROVE_RAW_LOCK_NESTING with PROVE_LOCKING.
With the printk issues solved, the last known splat created by PROVE_RAW_LOCK_NESTING is gone. Enable PROVE_RAW_LOCK_NESTING by default as part of PROVE_LOCKING. Keep the defines around in case something serious pops up and it needs to be disabled.

help
Enable the raw_spinlock vs. spinlock nesting checks which ensure
that the lock nesting rules for PREEMPT_RT enabled kernels are
not violated.
- NOTE: There are known nesting problems. So if you enable this
- option expect lockdep splats until these problems have been fully
- addressed which is work in progress. This config switch allows to
- identify and analyze these problems. It will be removed and the
- check permanently enabled once the main issues have been fixed.

- If unsure, select N.
