This enables OP-TEE support for i.MX93. This is done in a way very similar to how it's done on i.MX8M. One major difference is that the i.MX93 needs a RAM firmware for the EdgeLock secure enclave. Without it OP-TEE doesn't work properly. The firmware can be integrated into the i.MX93 image where the ROM picks it up automatically. The firmware image is SoC revision specific though, so we load the firmware during runtime to avoid having to create a barebox image for each SoC revision.
