[PATCH] sky2: use device iomem to access PCI config
To avoid problems with PCI config access without ACPI (or busted ACPI tables),
use the device's window into PCI config space.
I know this probably will upset the purists, but I would rather have users
than ACPI testers. It also generates less code.
