I didn't implement them because they don't make sense IMHO: the PCMCIA
bus on the Amiga is 16-bit wide. I seem to recall that wdc checked
before using the _4 variants if the underlying bus is 32-bit
capable. Maybe this has changed.
I can't investigate right now, but finding the caller of this
bus_space_read_multi_4() is the right first step to know if it's
legitimate. If it is, we can probably implement the functions easily.
