Subject: [PATCH v3 5/5] arch,locking/atomic: xtensa: define arch_cmpxchg_local as __cmpxchg_local

The xtensa architecture already has __cmpxchg_local defined but not used.
The purpose of __cmpxchg_local() is solely for arch_cmpxchg_local(), just
as the definition of arch_cmpxchg_local() for other architectures like x86,
arm and powerpc.
