You cannot use GPI/O with OpenCL unless the BSP already supports communicating with them in form of an I/O channel, or you yourself add support for it in the BSP. I don't think Terasic's BSP supports the GPI/O on the board; hence, you have no choice but to modify the BSP and add support for it yourself.

This is Altera's document on porting OpenCL BSP for Cyclone V SoCs:
