Implements "auto" shutter-speed otherwise there is no turning back

This patch adds the "auto" shutter-speed after the fastest mode.

I think this is sony specific and don't know if this is the right
solution.

Move ISO Value hints to separate strings

overlays. Otherwise the device overlay must provide all locales
provided by focal to take precedent.

PS2: Added old strings to existing translations

PS4: Rebased
