Subject: [PATCH v14 04/10] iommu/arm-smmu-v3: Make symbols public for CONFIG_TEGRA241_CMDQV

The symbols __arm_smmu_cmdq_skip_err(), arm_smmu_init_one_queue(), and
arm_smmu_cmdq_init() need to be used by the tegra241-cmdqv compilation
unit in a following patch.

Remove the static and put prototypes in the header.
