Update this driver to support driver model. As all MVEBU boards using this driver are converted with this patch, the non-driver-model code can be removed completely. This is also the reason why this patch is quite big and includes a) the driver change and b) the platform change. As its not git-bisect save otherwise. With this conversion, some parameters are now extracted from the DT instread of using the config header defines. The supported properties right now are: PHY-mode ("phy-mode") and PHY-address ("reg"). The base addresses for the ethernet controllers can be removed from the header files as well. Please note that this patch also removes the E1000 network driver from some MVEBU config headers. This is necessary, as with DM_ETH configured and the e1000 driver enabled, the PCI driver also needs to support DM. But the MVEBU PCI(e) driver still needs to get ported to DM. When this is done, the E1000 driver can be enabled again.
