microblaze: move the ARCH_{DMA,SLAB}_MINALIGN definitions to asm/cache.h 

The microblaze architecture defines ARCH_DMA_MINALIGN in asm/page.h.  Move
it to asm/cache.h to allow a generic ARCH_DMA_MINALIGN definition in
linux/cache.h without redefine errors/warnings.

While at it, also move ARCH_SLAB_MINALIGN to asm/cache.h for
consistency.
