powerpc/eeh: Remove eeh_dev.c

The only thing in this file is eeh_dev_init() which is allocates and
initialises an eeh_dev based on a pci_dn. This is only ever called from
pci_dn.c so move it into there and remove the file.

- * 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.
