parport: Use request_muxed_region for IT87 probe and lock

This is needed as part of making the various IT87 drivers actually co-exist
politely with each other, and with other superio devices that may be muxed
on 0x2E/0x2F.

It can be applied before or after the other patches by Nat Gurumoorthy without
problem.
