Please disregard this patch, it shows that my other patch
"meson: Introduce target-specific Kconfig" is incorrect:
https://lists.gnu.org/archive/html/qemu-devel/2021-01/msg07989.html
Probably because per docs/devel/kconfig.rst "devices are usually
``default y`` if and only if they have at least one ``depends on``".

I'll try another approach such:
