CONFIG_SPL_OPTEE_IMAGE option is used during DRAM size detection for Rockchip ARM platform to indicate that an OP-TEE binary was already loaded and a Trusted Execution Environment (TEE) is available in order to block/reserve a memory-region for it. This adds a bunch of new `#if's` to u-boot-rockchip.dtsi to include the OP-TEE binary in the FIT image for ARM SOCs if CONFIG_SPL_OPTEE_IMAGE is selected. That makes it a little harder to read, but I opted for that, because all the duplicates in an extra ARM-OP-TEE-specfic .dtsi would be the greater evil, IMHO. Besides it's more likley being "forgotten" to sync when changes in u-boot-rockchip.dtsi are made. The no longer required rockchip-optee.dtsi and it's inclusions are dropped. The hardcoded load address is common across all OP-TEE implemenations for Rockchip (vendor and upstream). The OP-TEE-binary is non-optional if CONFIG_SPL_OPTEE_IMAGE is selected and there will be an error if the file does not exist and/or `TEE=` build option is missing.
