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.

For architectures that support native cmpxchg, we'd like to
implement arch_cmpxchg[64]_local with the native variants of
supported data size. If not, the generci_cmpxchg[64]_local
will be used.
