--------------
Usage:
pci_save_state(dev, buffer);
pci_save_state(struct pci_dev *dev);
Description:
Save first 64 bytes of PCI config space. Buffer must be allocated by
caller.
Save first 64 bytes of PCI config space, along with any additional
PCI-Express or PCI-X information.
pci_restore_state
-----------------
Usage:
pci_restore_state(dev, buffer);
pci_restore_state(struct pci_dev *dev);
Description:
Restore previously saved config space. (First 64 bytes only);
If buffer is NULL, then restore what information we know about the
device from bootup: BARs and interrupt line.
Restore previously saved config space.

-------------------
Usage:
pci_set_power_state(dev, state);
pci_set_power_state(struct pci_dev *dev, pci_power_t state);
Description:
Transition device to low power state using PCI PM Capabilities
