[U-Boot] [PATCH v3 2/5] net/designware: ensure device private data is DMA aligned.

[Ian Campbell]

struct dw_eth_dev contains fields which are accessed via DMA, so make sure it
is aligned to a dma boundary. Without this I see:
    ERROR: v7_dcache_inval_range - start address is not aligned - 0x7fb677e0

v2: Sign of with my own mail not my work mail. I made these changes on my
own time, but a .gitconfig vcsh mismerge caused "git commit -s" to use the
wrong thing. (I wondered why everyone was CCing me at work...)
