This series patches mainly for ARM64 supporting.
To do this, it first add virtual iommu slave device which DRM can attach to,
convert DRM driver to use common iommu API instead of the ARM32
functions, and then use DMA API in iommu driver to map, to flush cache.
Mainly changes of V3:
- Instead of registering virtual iommu in DTS, V3
creates a iommu when attaching.
- Fix some bugs according to Tomasz's comments,
most of them are offline, locally.
