Activate ARCH_SUPPORT_TFABOOT and replace the arch stm32mp specific config CONFIG_STM32MP1_TRUSTED by the generic CONFIG_TFABOOT introduced by the commit 535d76a12150 ("armv8: layerscape: Add TFABOOT support"). This config CONFIG_TFABOOT is activated for the trusted boot chain, when U-Boot is loaded by TF-A.

Applied to u-boot-stm/next

Thanks
