Do not create kmalloc() caches which are not aligned to
dma_get_cache_alignment().  There is no functional change since for
current architectures defining ARCH_DMA_MINALIGN, ARCH_KMALLOC_MINALIGN
equals ARCH_DMA_MINALIGN (and dma_get_cache_alignment()).  On
architectures without a specific ARCH_DMA_MINALIGN,
dma_get_cache_alignment() is 1, so no change to the kmalloc() caches.
