MIPS: Lantiq: Add ethernet driver
This patch adds the driver for the ETOP Packet Processing Engine (PPE32) found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit ethernet work. Support for all 8 dma channels, gbit and the embedded switch found on the ar9/vr9 still needs to be implemented.
