arm64: tegra: Changes for v6.20-rc1

This update improves Device Tree support for 64-bit Tegra platforms,
specifically focusing on the Smaug board and the Tegra264 SoC. It
enables full USB-C functionality on Smaug by adding role-switching
support and enabling DisplayPort altmode. For Tegra264, it introduces
nodes for Command Queue Virtualization (CMDQV) in the SMMU, adds the
Data Backbone (DBB) clock for the memory controller, and corrects CPU
compatible strings to match the Neoverse V3AE core. Additionally, it
performs a cleanup by removing redundant status = "okay" properties
across Tegra186, Tegra194, Tegra234, and Tegra264 files.
