This member of the boardinfo isn't really necessary. All the boards
except the pci1713 have 16 digital inputs and 16 digital outputs.
There is already a 'is_pci1713' member in the boardinfo so that can
be used to determine the subdevices for the digital inputs and outputs
need to be allocated and initialized.
