aarch64/arm: Make _CPU_Fatal_halt() BSP-specific
Summary
In general, for test runs the system should reset once the test program terminated. The system reset implementation is BSP-specific. This makes _CPU_Fatal_halt() essentially a dead function since it is invoked after the BSP fatal extension which resets the system. To avoid this issue make the _CPU_Fatal_halt() implementation BSP-specific (similar to riscv and sparc).
Update #5010 (closed) and #5011 (closed).
