ARM: tegra: iovmm: Make IOMMU/IOVMM selectable in Kconfig
This patch enables to replace iovmm*.ko family with
tegra-{smmu,gart}.ko if needed in kernel config. To use IOMMU as
backend engine, Enable TEGRA_IOMMU_{GART,SMMU} under IOMMU in config,
and automatically disable IOVMM.
IOVMM is equivalent to IOMMU_API. TEGRA_IOVMM_GART is equivalent to
TEGRA_IOMMU_GART. TEGRA_IOVMM_SMMU is equivalent to TEGRA_IOMMU_SMMU.
