During a normal shutdown, gracefully tear down arbitrary stacks of
filesystems and (pseudo-)devices, according to the algorithm at A3
and A4, below.

In particular, cpu_reboot() now runs config_detach_all(), while acpi(4) can
not obviously be detached as it is responsible for the hardware powerdown.
It was also disucssed that removing the dopowerhooks() could be unsafe (even
At the moment it is unclear how this should be resolved.
