  4. plat-stm32mp1: conf: disable CRYP when SAES is enable on STM32MP13. 

    override value of CFG_STM32_CRYP to n when CFG_STM32_SAES=y.
OP-TEE crypto framework can only register one AES accelerator.
If CRYP and SAES are probed, OP-TEE will panic.

  8. drivers: stm32_saes: remove probe verification on base address 

    An assert was used to ensure we only probe one instance of SAES.
It can create an error if the probe is deferred.
Remove assert as it can create an error and the probe will fail when
registering in the crypto framework.
