Add a new 'clear driver' command for devctl along with the accompanying ioctl and devctl_clear_driver() library routine to reset a device to use a wildcard devclass instead of a fixed devclass. This can be used to undo a previous 'set driver' command. After the device's name has been reset to permit wildcard names, it is reprobed so that it can attach to newly-available (to it) device drivers.
