microblaze: Support DMA
Add DMA support for Microblaze. There are some part of this new feature:
1. Basic DMA support
2. Enable DMA debug option
3. Setup notifier
Ad 1. dma-mapping come from powerpc and x86 version and it is based on
generic dma-mapping-common.h
Ad 2. DMA support debug features which is used in generic file.
For more information please look at Documentation/DMA-API.txt
Ad 3. notifier is very important to setup dma_ops. Without this part
for example ll_temac driver failed because there are no setup dma operations.
