ARM: v6k: select cmpxchg code sequences according to V6 variants
If CONFIG_CPU_V6 is enabled, we must avoid the byte/halfword/doubleword
exclusive operations, which aren't implemented before V6K. Use the
generic versions (or omit them) instead.
If CONFIG_CPU_V6 is not set, but CONFIG_CPU_32v6K is enabled, we have
the K extnesions, so use these new instructions.
