ARM64: zynqmp: Use the same U-Boot version with/without ATF
Remove SECURE_IOU option which is not needed. U-Boot itself can detect which EL level it is on and based on that use do platform setup. It also simplify usage because one Kconfig entry is gone. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
