We can only support UP on mips o32 going forward as 64-bit atomics are needed. Remove it with prejudice, and a future change will effectively kill the ability to compile mips o32 w/ SMP defined.

Remove the xdma change, don't remove the comments at the top that indicated that this hardware is SMP-capable (but we don't support it).

No need just yet... mips o32 will use the implementation cooked up by Justin/Brandon for ppc32 using a lock pool.
