layered parport code uses parport->dev

Update some of the layered parport_driver code to use parport->dev:

	- i2c-parport (parent of i2c_adapter)
	- spi_butterfly (parent of spi_master, allowing cruft removal)
	- lp (creating class_device)
	- ppdev (parent of parportN device)
	- tipar (creating class_device)

There are still drivers that should be updated, like some of the input
drivers; but they won't be any worse off than they are today.
