sky2: revert to access PCI config via device space
Using the hardware window into PCI config space is more reliable and smaller/faster than using the pci_config routines. It avoids issues with MMCONFIG etc. Reverts: 167f53d05fccb47b6eeadac7f6705b3f2f042d03 Please apply for 2.6.24 Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
