according to the flash datasheet, the I/O's can range from 1.65 to Vcc.

Since you want to use at 2.5v interface for fpga IO's, you are ok to select the Vio to 2.5v.

make sure you follow the configuration guide to check if you followed the recommendations.

CFGBVS needs to be connected to Vcco. 

check table 2-6 from the following link
