Patch/resubmit(2.5.50): Eliminate pci_dev.driver_data

From: Adam J. Richter (adam@yggdrasil.com)

        This is the third time I'm posting this patch. The only
comments anyone has made about it were from Greg Kroah-Hartmann, which
were in favor of integrating it. Can we please get this integrated
already? I want to try some more changes to pci.h and I'd rather keep
the patches separate.

        To review, this patch deletes pci_dev.driver_data, using the
existing pci_dev.device.driver_data field instead, thereby shrinking
struct pci_dev by four bytes on 32-bit machines. The few device
drivers that attempted to directly reference pci_dev.driver_data were
fixed in a patch of mine that Jeff Garzik got into 2.5.45. Also,
making this change should help with memory allocation improvements in
the future, although that's a separate issue.
