ioport: remove LITTLE_ENDIAN mark for portio
Setting it to LE forces a byte swap when host != guest endian but this makes no sense at all. Herve made the suggestion upon observing that word writes/reads were broken into byte writes/reads in such a way as to assume devices are interpret registers as LE. However, even if this were a problem, marking the region as LE is not useful because what's essentially happening here is that LE is open coded. So by marking it LE in MemoryRegionOps, we're doing a superflous swap. Now, the portio code is suspicious to begin with. The dispatch layer really has no purpose in splitting I/O requests in the first place...
