Generally, follow the recommendation for connection of unused pins given in the *.pin file.

I'm rather sure, that Altera expects all GXB power pins to be connected with voltages according to the specified operation conditions, independent of the actual GXB block usage. It's the same e.g. with PLL supplies. Quartus is automatically configuring all ununsed resources to power-down mode.
