They should probably switch to device_get_sysctl_*(), with some compat
glue to ease the transition.

If you remember to always pass the device's sysctl context to
SYSCTL_ADD_*() when you create the nodes, they will be GCed when the
device detaches (even if they are outside the device's sysctl subtree)

We should probably have per-class contexts as well, so stuff like
hw.snd.unit can be placed directly under dev.pcm.
