The GPIO_, GPI_ and GPO_ prefixes corresponds to the different
flavours. Do they still need a common prefix? Ie. the GPI_REG_IN
has nothing to do with GPO_REG_OUT, nor has both something
to do with the GPIO_REG_IN and GPIO_REG_OUT. I could prefix them
with SL28CPLD_ though. But I don't know if that is what you had
in mind because then they would be SL28CPLD_GPIO_REG_IN and
SL28CPLD_GPI_REG_IN for example.
