ARC: arch_cmpxchg_relaxed to use size of pointed type not pointer

Bradley spotted this snafu when working on two-byte cmpxchg emulation.
He originally folded this fix into his series but the fix itself
uncovered a pre-existing issue, missing arch_atomic64_cmpxchg_relaxed
which just needed to be wired up.
