Update Versal platform to enable runtime detection of variants instead of relying on the build argument VERSAL_PLATFORM. Integrate functionality for identifying the board variant during runtime, allowing dynamic adjustment of CPU and UART clock values accordingly. Print the runtime board information during boot. This advancement streamlines the build process by eliminating dependencies on variant-specific builds, enabling the use of a single binary for multiple variants. Removing all the platform related constants for versal_virt,SPP,EMU as they are not used.
