Support external keyboards in osk-sdl on PinePhone
Now the PinePhone convergence edition has start arriving for people, they'll start using it with external keyboards (and more peripherals). Currently osk-sdl doesn't support external keyboards, no input is registerd, but it would be great if it did so you don't have to pick up the phone and use the touchscreen to do something that you can normally do with a keyboard.
