Update the PinePhone keyboard driver to support missing characters?

[Hook]

For whatever it is worth in this context, for PostmarketOS with SXMO, the keyboard works perfectly out of the bix. AltG gets you the third layer symbols on the numkeys and Pine-numkey gets you the function keys. No mods of any sort required. Being a noob, SXMO was a little challenging, but once you get it, it is perfect for a phone sized device. I just installed nano and away I go. SXMO on a PinePhone makes the phone essentially a terminal with menus and gestures. Very nice.

I don't use Libre Office at all, so I haven't tried that.
