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.

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).

Check whether user has explicitly defined the mmc device to use
in mmc_get_env_dev() with CONFIG_SYS_MMC_ENV_DEV.
On STMicroelectronics boards the used mmc device for environment is
the instance of boot device provided by the ROM code; the mmc instance
is configured by alias in device tree. The used partition is defined in
device tree with u-boot,mmc-env-partition = "ssbl".
This patch allows to override this selection for the support of customer
boards without alias; for example when SDMMC1 is not used and ENV in
mmc0=SDMMC2, user can force the value: CONFIG_SYS_MMC_ENV_DEV = 0.
On STMicroelectronics boards, the current behavior is kept with
CONFIG_SYS_MMC_ENV_DEV = -1.

Add a specific command stm32prog for STM32MP soc family
witch allows to program the boot devices with the tool
STM32CubeProgrammer (http://www.st.com/STM32CubeProg).
This command uses the same UART STM32 protocol than MCU
STM32 with or USB with DFU protocol v1.1 (ithe MCU ST
extension are no supported).
The executed actions are based on a tab separated value file
with a stm32 header, the FlashLayout file
(https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout).
This file is parsed by the U-Boot command to:
- initialize the devices
- create the partition table on each device
- initialize the DFU backend to access to not volatile memory
(NOR/NAND/SD/eMMC) or to virtual device (OTP/PMIC)
Up to STM32PROG_MAX_DEV (5) devices can be updated with a FlashLayout.
The communication between U-Boot and STM32CubeProgrammer is done with
the specific alternate configuration (see "AN5275: USB DFU/USART protocols
used in STM32MP1 Series bootloaders" for details).
The command stm32prog is executed when a boot from USB is detected
(selected with bootpins) and we can program the boot devices with
a simple command (on Windows or Linux):
PC $> STM32_Programmer_CLI -c port=usb1 -w flaslayout.tsv
1/ the ROM code loads TF-A in embedded RAM (DFU or uart)
2/ TF-A loads flashlayout file and U-Boot in DDR (DFU or uart)
