sh: mach-edosk7705: update for this century, kill off PIO trapping.
The only reason this board needs to do PIO trapping is for ethernet,
which happens to follow the same scheme as its bigger brother the
edosk7760. With ethernet properly supported through the platform device,
we can kill off the left over PIO abortion.
