[13/16] ARM: shmobile: Genmai: set proper DMA masks for Ether device

Message ID 583e2448629cc9fb3b1a0c850ddbe06819421d3e.1392960310.git.horms+renesas@verge.net.au (mailing list archive)

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and
'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing
ability.
