stm32mp1: dynamically detect op-tee presence

Activate OP-TEE driver for trusted and optee defconfig.

This driver allows detection of TEE presence for boot from flash;
CONFIG_STM32MP1_OPTEE is also removed.

Say Y here to enable boot with TF-A and OP-TEE
Trusted boot chain is :
BootRom => TF-A.stm32 (clock & DDR) => OP-TEE => U-Boot.stm32
