[PATCH 3/4] mips: set DMA_ALIGNMENT instead of defining dma_alloc

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

<dma.h> will take care to define dma_alloc with DMA_ALIGNMENT as
alignment. As 32 is the default and may not be applicable to the used
processor, we define DMA_ALIGNMENT and drop the now duplicate code.
