[Qemu-trivial] [PATCH] qemu-system-tricore: segfault when entering "x 0" on the monitor |

Starting Qemu with "qemu-system-tricore -nographic -M tricore_testboard
-S" and entering "x 0" at the monitor prompt leads to Segmentation
fault. This happens because tricore_cpu_get_phys_page_debug() is not
implemented yet, this is a temporary workaround to avoid the crash do
just abort the execution with exit(1).
