net: ethernet: ixp4xx: Set the DMA masks explicitly
The former fix only papered over the actual problem: the
ethernet core expects the netdev .dev member to have the
proper DMA masks set, or there will be BUG_ON() triggered
in kernel/dma/mapping.c.
Fix this by simply copying dma_mask and dma_mask_coherent
from the parent device.
