* gpio_base3_value(), whereas the other two pins are not connected
* and read as 'two'. This results in gpio_base3_value() returning
* 8 on proto0.
*
* Three tertitiary signals could represent 27 different values. To make
* calculated board ID value continuous and starting at zero, offset the
* calculated value by 19 (i.e. 27 - 8) and return modulo 27 of the offset
