[PATCH] ARM/dma-mapping: Disambiguate ops from iommu_ops in IOMMU core

[Easwar Hariharan <eahariha@linux.microsoft.com>]

The architecture dma ops collides with the struct iommu_ops {} defined in
/include/linux/iommu.h. This isn't a major issue, just a nagging annoyance.

Rename iommu_ops to arm_dma_iommu_ops to disambiguate and better match the
other architectures. No functional changes intended.
