Subjectfully convert arm to use dma-direct v2
Date
Hi all,

arm is the last platform not using the dma-direct code for directly
mapped DMA. With the dmaboune removal from Arnd we can easily switch
arm to always use dma-direct now (it already does for LPAE configs
and nommu). I'd love to merge this series through the dma-mapping tree
as it gives us the opportunity for additional core dma-mapping
improvements.

Changes since v1:
- remove another unused function
- improve a few commit logs
- add three more patches from Robin
