[patch V3 25/64] locking/lockdep: Reduce includes in debug_locks.h

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

The inclusion of printk.h leads to a circular dependency if spinlock_t is
based on rtmutexes on RT enabled kernels.

Include only atomic.h (xchg()) and cache.h (__read_mostly) which is all
what debug_locks.h requires.
