device_get_children — get a list of devices connected to a device
device_get_children(device_t dev, device_t **devlistp, int *devcountp);
Retrieve a list of all device instances currently connected to dev and
return the list in *devlistp and the count in *devcountp. The memory
allocated for the list should be freed using free(*devlistp, M_TEMP).
devlistp and devcountp are not changed when an error is returned.
Zero is returned on success, otherwise an appropriate error is returned.
