[patch 20/50] locking/rtmutex: Prevent future include recursion hell

[Thomas Gleixner]

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

rtmutex only needs raw_spinlock_t, but it includes spinlock_types.h which
is not a problem on an non RT enabled kernel.

RT kernels substitute regular spinlocks with 'sleeping' spinlocks which
are based on rtmutexes and therefore must be able to include rtmutex.h.

Include spinlock_types_raw.h instead.
