1. Addition of Coresight support on Juno R1 and R2 variants
2. Addition of STM(System Trace Macrocell) support on all Juno variants
3. Removed incorrect nesting of dtsi files
4. Removed untested USB hub only available on initial Juno R0 motherboard
5. Added ETR SMMU power domain and dma-ranges property
