Will Deacon d0d583484d locking/refcount: Consolidate implementations of refcount_t 
[ Upstream commit fb041bb7c0 ]

The generic implementation of refcount_t should be good enough for
everybody, so remove ARCH_HAS_REFCOUNT and REFCOUNT_FULL entirely,
leaving the generic implementation enabled unconditionally.
