parport->dev driver model support
Currently a parport_driver can't get a handle on the device node for the underlying parport (PNPACPI, PCI, etc). That prevents correct placement of sysfs child nodes, which can affect things like power management. This patch adds a field to "struct parport" pointing to that device node, and updates non-legacy port drivers to initialize that device pointer. That field replaces the analagous PCI-only support in parport_pc.
