microblaze: use the generic dma coherent remap allocator
This switches to using common code for the DMA allocations, including potential use of the CMA allocator if configured. Switching to the generic code enables DMA allocations from atomic context, which is required by the DMA API documentation, and also adds various other minor features drivers start relying upon. It also makes sure we have on tested code base for all architectures that require uncached pte bits for coherent DMA allocations.
