Linus Walleij 257f38e78a net: ethernet: ixp4xx: Set the DMA masks explicitly ...

[ Upstream commit 8d892d6094 ]

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.
