Ah, that must have happened with cgd's device_t-ification. cgd needs to
register with PMF when it attaches, and to deregister when it detaches.

NULL suspend & resume handlers *may* be appropriate for cgd, but let's
see some justification of that.  Consider whether the driver will do
something unexpected if you suspend/resume it in isolation, using
drvctl.
