In theory you can use more of the Pins as GPIOs. But at this point I 
should mention that the Segin board became slightly more complicated 
since it started to support more SoMs with different SoCs. We have 
routings for various pins to help with the compatibility. So the naming 
in the schematics is not really trivial. And IMO the dt should follow 
the naming of the schematics.

I would prefer to go with v5 without having any namings for now.
