staging: comedi: addi_apci_16xx: redefine the boardinfo

Browse Source 
Currently this driver uses the struct addi_board from the addi-data
"common" code to define the boardinfo. This struct contains a lot
of information that is not used in this driver.

Introduce a private struct in the driver that just contains the
needed information.
