aarch32: optee: define the OP-TEE secure payload
AArch32 only platforms can boot the OP-TEE secure firmware as a BL32 secure payload. Such configuration can be defined through AARCH32_SP=optee. The source files can rely on AARCH32_SP_OPTEE to condition OP-TEE boot specific instruction sequences. OP-TEE does not expect ARM Trusted Firmware formatted structure as boot argument. Load sequence is expected to have already loaded to OP-TEE boot arguments into the bl32 entrypoint info structure. Last, AArch32 platform can only boot AArch32 OP-TEE images.
