This patch replaces ARM-specific IOMMU-based DMA-mapping implementation
with generic IOMMU DMA-mapping code shared with ARM64 architecture. The
side-effect of this change is a switch from bitmap-based IO address space
management to tree-based code. There should be no functional changes
for drivers,
