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...
