Add spidev nodes to two existing SPI controllers on the NVIDIA Tegra234 SoC. These additions enable user-space SPI device support for testing and development purposes. Specifies a maximum frequency of 81MHz for each spidev node. The 81MHz maximum frequency is defined to ensure stable operation while allowing for high-speed SPI communication. This frequency can be adjusted based on specific hardware capabilities and requirements.
