feat(st): add a configuration without AARCH32_SP

On STM32MP15, we can choose either SP_MIN or OP-TEE as BL32. BL2 can be
compiled without the knowledge of the BL32 used, it is detected at
runtime. A new configuration is added for this BL2 compilation. It
follows the discussion for a patch checking AARCH32_SP:
