staging: comedi: addi_apci_3120: remove i_APCI3120_InsnConfigDigitalOutput() 

The digital outputs of the board supported by this driver are not
configurable. This driver abuses the comedi API and uses the 'insn_config'
function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.
