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. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
