Hiroshi DOYU d53e54b4d4 ARM: IOMMU: Tegra20: Add iommu_ops for GART driver 
Tegra 20 IOMMU H/W, GART (Graphics Address Relocation Table). This
patch implements struct iommu_ops for GART for the upper IOMMU API.

This H/W module supports only single virtual address space(domain),
and manages a single level 1-to-1 mapping H/W translation page table.
