stm32mp1: add trusted boot with TF-A
Add support of trusted boot, using TF-A as first stage bootloader,
The boot sequence is
BootRom >=> TF-A.stm32 (clock & DDR) >=> U-Boot.stm32
The TF-A monitor provides secure monitor with support of SMC
- proprietary to manage secure devices (BSEC for example)
- PSCI for power
The same device tree is used for STMicroelectronics boards with
basic boot and with trusted boot.
