According to the datasheet, CYUSB202x's GPIO is connected to USB Endpoints directly. Is it GPIF? or is it same as other FX3 parts for USB Endpoints access externally? I want to use external FPGA to access USB Endpoints through CYUSB202x's GPIO.

No, the GPIOs are not connected directly to the endpoints. The actual architecture is similar to FX3 which you can read about in Chapter 3 of the FX3 Programmer's Manual.
If you want to do transfers, then using GPIOs is not recommended. It will be very very slow and will involve a lot of code. You can instead use GPIF (for which you need FX3S). Otherwise, you can use SPI, I2C, UART or one of the SD ports.
