SF: Do not deref empty std::optional<PowerMode> In I3a2eae4efc4a5c6113700a9ca9e9b261e364a878, a display's power mode is std::nullopt (unknown) until the first setPowerMode. The condition to power on the display from that state relies on undefined behavior, as it dereferences std::nullopt. It only works because PowerMode::OFF is 0 and the memory happens to be zeroed.
