soc_xilinx_versal driver allows identification of family & revision of versal SoC. This driver is selected by CONFIG_SOC_XILINX_VERSAL. Probe this driver using platdata U_BOOT_DEVICE structure which is defined at mach-versal/cpu.c. Add this config to xilinx_versal_virt_defconfig & xilinx_versal_mini_ospi_defconfig file to select this driver.
