SPINEL_CMD_RESET value

Reset NCP command (Host -> NCP) Encoding: Empty or `C` Causes the NCP to perform a software reset. Due to the nature of this command, the TID is ignored. The host should instead wait for a `CMD_PROP_VALUE_IS` command from the NCP indicating `PROP_LAST_STATUS` has been set to `STATUS_RESET_SOFTWARE`. The optional command payload specifies the reset type, can be `SPINEL_RESET_PLATFORM`, `SPINEL_RESET_STACK`, or `SPINEL_RESET_BOOTLOADER`. Defaults to stack reset if unspecified. If an error occurs, the value of `PROP_LAST_STATUS` will be emitted instead with the value set to the generated status code for the error.
