        src/sys/dev/fdt: virtio_mmio_fdt.c

Log Message:
virtio@acpi, virtio@fdt: Nix DVF_DETACH_SHUTDOWN.

There is no reason to force _all_ devices attached at the virtio bus
to detach at shutdown.  This only makes sense for devices that
require detach in order to force buffered writes to persistant
storage so we don't lose them (or, in principle, require detach in
order to release hardware resources).

And the only virtio devices I found that require detach-on-shutdown,
namely scsi@virtio, already set DVF_DETACH_SHUTDOWN, so there's no
need for the bus to do it.  (The only other obvious case, ld@virtio,
uses a pmf shutdown handler instead of detach, so it doesn't need
DVF_DETACH_SHUTDOWN.)
