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.
