I only gave the Seaboard GPIOs symbolic names because they all ended up
being used in multiple places; in this GPIO table, in platform data,
etc. Given that Ventana is a DT-only board, and this is the only place
that the GPIOs will ever be named by code rather than *.dts files, does
it make sense to require symbolic names? If you do think so, I don't
really have any objection to making names.
