This was copied from the qe_config_iopin function, which still used the
volatile directive. I can fix it there as well, but I see that it's used
everywhere. Maybe this needs a thorough change, but I'm not sure it
should be in my humble patch.

Hehe - will change.

Will change as well. I think ioports.h is good enough for this purpose.
So far, qe_config_iopin wasn't there as well, so it will also be moved
there.
