To allow to move to orion irqchip driver, existing legacy devices have to map their irqs. This patch adds a node for mv643xx_eth and some init code to map the corresponding irqs. While the device tree node can stay, the init code will vanish as soon as there is true device tree support for mv643xx_eth.
