Some third party tools (ex. ubxtool) tries to change GNSS TTY parameters (ex. speed). While being optional implementation, without set_termios handle this operation fails and prevent those third party tools from working. TTY interface in ice driver is virtual and don't need any change on set_termios, so is left empty. Add this mock to support all Linux TTY APIs.
