PCI : remove too specialized __pci_enable_device for default resume

Original patch was posted as "PCI : Move pci_fixup_device and is_enabled".
This 1 of 3 patches does:

  - reverts small part of Inaky's patch
    (remove __pci_enable_device)
    This change will be recovered by 3rd patch.

  - temporarily remove pci_fixup_device.
    This change will be recovered by 2nd patch.
