Suman Anna 63c7ecd7b1 ARM: dts: DRA74x: Add IOMMU nodes for DSP2
The DRA74x family of SoCs have a second DSP, that also has
two MMUs just like the DSP1 subsystem. Add the IOMMU nodes
for this DSP2 subsystem in disabled state to the DRA74x
specific DTS file, the nodes would need to be enabled
appropriately in the respective board DTS files.
