soc: xilinx: versal: Add soc_xilinx_versal driver
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.
