Subject: [PATCH 144/196] PCI: remove foolish code from pci-driver.c

The PCI bus should not be trying to declare its own attribute type.
Especially as this code could never ever be called because the driver
core overwrites the driver kobject type to be its own internal type.
Delete all of this code as it was never being used and is not correct.

Also update my copyright on the file while I'm touching things there.
