Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

- * The file intends to implement dynamic creation of EEH device, which will
- * be bound with OF node and PCI device simutaneously. The EEH devices would
- * be foundamental information for EEH core components to work proerly. Besides,
- * We have to support multiple situations where dynamic creation of EEH device
- * is required:
- *
- * 1) Before PCI emunation starts, we need create EEH devices according to the
- * PCI sensitive OF nodes.
- * 2) When PCI emunation is done, we need do the binding between PCI device and
- * the associated EEH device.
- * 3) DR (Dynamic Reconfiguration) would create PCI sensitive OF node. EEH device
- * will be created while PCI sensitive OF node is detected from DR.
- * 4) PCI hotplug needs redoing the binding between PCI device and EEH device. If
- * PHB is newly inserted, we also need create EEH devices accordingly.
