As a first step, implement the bare minimum: CPUs, RAM, interrupt controller,
serial. All other devices of the A53 memory map are represented as
TYPE_UNIMPLEMENTED_DEVICE, i.e. the whole memory map is provided. This allows
for running Linux without it crashing due to invalid memory accesses.

Hi Bernhard, hi Peter,
this device can be used to crash QEMU quite easily:
$ ./qemu-system-aarch64 -M virt -device fsl-imx8mp
**
ERROR:../../devel/qemu/tcg/tcg.c:1006:tcg_register_thread: assertion failed:
(n < tcg_max_ctxs)
Bail out! ERROR:../../devel/qemu/tcg/tcg.c:1006:tcg_register_thread:
assertion failed: (n < tcg_max_ctxs)
Aborted (core dumped)
Should it maybe be marked with "user_creatable = false" to avoid this?
