By default for trusted boot with TF-A, U-Boot (u-boot-nodtb) is located in FIP container with its device tree and with the secure monitor (provided by TF-A or OP-TEE). The FIP file is loaded by TF-A BL2 and each components is extracted at the final location.

This patch add CONFIG_STM32MP15x_STM32IMAGE to request the STM32 image generation for SOC STM32MP15x when FIP container is not used (u-boot.stm32 is loaded by TF-A as done previously to keep the backward compatibility).

With FIP support in TF-A (when CONFIG_STM32MP15x_STM32IMAGE is not activated), the DT nodes needed by OP-TEE are added by OP-TEE firmware in U-Boot device tree, present in FIP.

These nodes are only required in trusted boot, when TF-A load the file u-boot.stm32, including the U-Boot device tree with STM32IMAGE header, in this case OP-TEE can't update the U-Boot device tree.

Moreover in trusted boot mode with FIP, as the OP-TEE nodes are present in U-Boot device tree only when needed the function stm32_fdt_disable_optee can be removed.

Add TF-A FIP support for trusted boot on STM32MP15x, when STM32MP15x_STM32IMAGE is not activated.

With FIP support the SSBL partition is named "fip" and its size is 4MB, so the ENV partition name in device tree (for SD card or eMMC) or offset in defconfig (CONFIG_ENV_OFFSET / CONFIG_ENV_OFFSET_REDUND) need to be modified.

With FIP the TEE MTD partitions are removed because the OP-TEE binray are included in the FIP containers.

TF-A for STM32MP15 now supports the FIP: it is a packaging format which includes the secure monitor, u-boot-nodtb.bin and u-boot.dtb

This FIP file is loaded by FSBL = TF-A BL2.

This patch updates the board documentation to use this FIP file and no more u-boot.stm32 (with STM32 image header) which is no more generated.

The MTD tee partitions used to save the OP-TEE binary are needed when TF-A doesn't use the FIP container to load binaries.

This patch puts under CONFIG_STM32MP15x_STM32IMAGE flag the associated code in U-Boot binary and prepare the code cleanup when CONFIG_STM32MP15x_STM32IMAGE support will be removed after TF-A migration to FIP support.
