Fix kmalloc alignment on non-coherent DMA platforms
[POWERPC] Fix kmalloc alignment on non-coherent DMA platforms

On platforms doing non-coherent DMA (4xx, 8xx, ...), it's important
that the kmalloc minimum alignment is set to the cache line size, to
avoid sharing cache lines between different objects, so that DMA to
one of the objects doesn't corrupt the other.
