You can use the MPSSE Engine to control those pins as GPIO.

See AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes for more details.

Alternatively you can use bit bang mode but you will be limited to 8 pins on the D bus and 4 pins on the ACBUS (9, 8, 6 and 5).
See the following documents for more information about bit bang mode:

AN232R-01 Bit Bang Modes for the FT232R and FT245R
AN_373 Bit-Bang Modes for the FT-X Series

These are for a different products but same principles apply.
