[PATCH] PCI: reverse pci config space restore order

According to Intel ICH spec, there are several rules that Base Address
should be programmed before IOSE  (PCICMD register ) enabled.

For example ICH7:

12.1.3  SATA : the base address register for the bus master register
               should be programmed before this bit is set.

11.1.3:  PCICMD (USB): The base address register for USB should be
                       programmed before this bit is set.
....

To make sure kernel code follow this rule , and prevent unnecessary
confusion. I proposal this patch.
