Davidlohr Bueso 5db6c6fefb locking/rwsem: Add CONFIG_RWSEM_SPIN_ON_OWNER ...

Just like with mutexes (CONFIG_MUTEX_SPIN_ON_OWNER),
encapsulate the dependencies for rwsem optimistic spinning.
No logical changes here as it continues to depend on both
SMP and the XADD algorithm variant.

[ Also make it depend on ARCH_SUPPORTS_ATOMIC_RMW. ]
