microblaze: use generic dma_noncoherent_ops
Switch to the generic noncoherent direct mapping implementation.
This removes the direction-based optimizations in
sync_{single,sg}_for_{cpu,device} which were marked untestested and
do not match the usually very well tested {un,}map_{single,sg}
implementations.
