When CONFIG_DM_ETH is enabled DPAA2 network interfaces will now probe based on DTS nodes with the "fsl,qoriq-mc-dpmac" compatible. In this case, transform the ldpaa_eth driver into a UCLASS_ETH driver and reuse the _open()/_tx()/_stop() functions already inplemented. For the moment, the ldpaa_eth driver will support both configurations: with or without CONFIG_DM_ETH enabled. Any 'struct eth_device' occurrence now has a matching 'struct udevice' made mutually exclusive based on the state of CONFIG_DM_ETH.
