nvmem: stm32: add OP-TEE support for STM32MP13x
For boot with OP-TEE on STM32MP13, the communication with the secure
world no more use STMicroelectronics SMC but communication with the
STM32MP BSEC TA, for data access (read/write) or lock operation:
- all the request are sent to OP-TEE trusted application,
- for upper OTP with ECC protection and with word programming only
each OTP are permanently locked when programmed to avoid ECC error
on the second write operation
