The Command Queue Virtualization (CMDQV) hardware is part of the SMMUv3 implementation on NVIDIA Tegra SoCs. It assists in virtualizing the command queue for the SMMU. Update SMMU compatible strings to use nvidia,tegra264-smmu to enable CMDQV support. Add device tree nodes for the CMDQV hardware and enable them on the tegra264-p3834 platform where SMMUs are enabled. Each SMMU instance is paired with its corresponding CMDQV instance via the nvidia,cmdqv property. Signed-off-by: Ashish Mhetre <redacted>
