When the RNG device is secured with OP-TEE, it is only accessible with
the HWRNG TA, the CONFIG_RNG_OPTEE is needed for STM32MP15 targets
with OP-TEE support.
The probe of this RNG driver fails when the TA is not available in OP-TEE
and the previous driver can be used, as CONFIG_RNG_STM32MP1 is activated
and when the associated node is activated in the device tree with:
&rng1 {
status = "okay";
};
When the RNG is used in OP-TEE, this node should be deactivated in
the Linux and U-Boot device tree.

The IPCC mailbox is only used for communication with M4 firmware but
it is not used in the stm32 remoteproc driver; it was planed but the
support of this mailbox in remoteproc for STM32MP15x is dropped.
So the associated drivers and config CONFIG_STM32_IPCC can be
deactivated to reduce the U-Boot size; the CONFIG_DM_MAILBOX can be
also deactivated as the mailbox UCLASS is no more used.

Enable an existing simple framebuffer node in the Linux kernel device
tree and the add the associated reserved memory node to preserved the
resources (clock, memory) used by the stm32 video driver to display
the splashscreen = background in exlinux.conf file.
These resources will be released by the Linux driver only when the
associated driver is ready to avoid transition issues during the Linux
kernel initialization between U-Boot splash screen and the final display.
See Linux documentation for details:

Remove the dependency on CONFIG_TFABOOT in stm32mp Kconfig
- always activate the ARCH config: CONFIG_ARCH_SUPPORT_PSCI
and CONFIG_CPU_V7_HAS_NONSEC
- CONFIG_ARMV7_NONSEC is deactivated in trusted defconfig
- the correct sysreset driver is activated in each defconfig:
CONFIG_SYSRESET_PSCI or SYSRESET_SYSCON

Use binman to add the stm32image header on SPL binary for basic boot
or on U-Boot binary when it is required, i.e. for TF-A boot without FIP
support, when CONFIG_STM32MP15x_STM32IMAGE is activated.
The "binman" tool is the recommended tool for specific image generation.
This patch allows to suppress the config.mk file and it is a preliminary
step to manage FIT generation with binman.
The init_r parsing of U-Boot device tree to search the binman
information is not required for STM32MP15, so the binman library
can be removed in U-Boot (CONFIG_BINMAN_FDT is deactivated).

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.
