    [AVR32] Define mmiowb()
    Add empty definition of mmiowb() since some drivers need it. Uncached
    writes are strongly ordered on AVR32. They may be delayed if the
    dcache is busy doing a writeback, but AFAICT that's not what this
    macro is supposed to deal with, at least on UP systems.
    We might have to revisit this definition when a SMP-capable AVR32 CPU
    comes along, depending on how the busses and cache coherency stuff
    end up being implemented.
