Make the support for starting in EL2/EL3 customizable. A boot loader or the Arm Trusted Firmware should start RTEMS in non-secure EL1 mode. In start.S, use local labels. For the aarch64/xilinx-zynqmp the support for starting in EL2/EL3 is disabled by default. For the Qemu xlnx-zcu102 machine, the default is to start in non-secure EL1 mode. This can be controlled by options, for example "-machine xlnx-zcu102,secure=on,virtualization=on".
