fix(stm32mp1-fdts): correct memory mapping for STM32MP13

On STM32MP13, OP-TEE will be loaded at the beginning of the secure
memory, and will be responsible for its shared memory.
The memory allocated to OP-TEE is then 32MB, and the shared memory
does no more appear in the STM32MP13 fw-config DT file.
