Use FIP #2

Attach the OP-TEE OS image as FIP to BL31. BL31 then needs to extract the image from the FIP.

This makes the OP-TEE OS image optional and no longer limited to 500 KiB.

hey, I would like to contribute if you could tell me more about the process?

Great! Find out how, for example, the Raspi3 fetches the Optee from the FIP and loads it onto BL32_BASE. Then implement the same for the RPi4, preferably in C. I'll try your fork then. If that works properly, you've done a great job.
