System tests on x86 use isa-debug-exit device in order to signal
success or failure to the test runner. Unfortunately it's not easily
usable on other architectures, since a guest needs to access
address_space_io, which may not be as straightforward as on x86.
Also, it requires adding ISA bus, which an architecture might not
otherwise need.
Introduce mmio-debug-exit device, which has the same semantics, but is
triggered by writes to memory.

You shouldn't need this for s390x, as there are already (at least) two other paths to
qemu_system_shutdown_request.
E.g. SIGP, which has a stop option.
