[PATCH v6 2/6] iommu/tegra-smmu: Rename struct tegra_smmu_group_soc *soc to *group_soc

[Nicolin Chen <nicoleotsuka@xxxxxxxxx>]

There are both tegra_smmu_soc and tegra_smmu_group_soc using "soc"
for their pointer instances. This patch renames the one of struct
tegra_smmu_group_soc from "soc" to "group_soc" to distinguish it.
