Kuo-Jung Su 771f74c3d3 arm: dma_alloc_coherent: malloc() -> memalign() ...

Even though the MMU/D-cache is off, some DMA engines still
expect strict address alignment.

For example, the incoming Faraday FTMAC110 & FTGMAC100 ethernet
controllers expect the tx/rx descriptors should always be aligned
to 16-bytes boundary.
