[PATCH] locking/lockdep: Enforce PROVE_RAW_LOCK_NESTING only if ARCH_SUPPORTS_RT

Relax the rule to set PROVE_RAW_LOCK_NESTING by default only for arches
that supports PREEMPT_RT. For arches that do not support PREEMPT_RT,
they will not be forced to address irrelevant raw lock nesting issues
when they want to enable PROVE_LOCKING.
