The STM32MP15 boards have no reason to configure bootdelay in stm32mp1.h
as it is already done with CONFIG_BOOTDELAY (default = 2) and in
include/env_default.h.
This patch allows configuration for customers which reuse stm32mp1.h
and reduce the size of the default environment.

The board can boot with UEFI. With the latest changes in U-Boot's
EFI subsystem we also have support for EFI runtime variables, without
SetVariable support. We can also store the EFI variables in a file on the
ESP partition and preserve them across reboots.
The env and efidebug commands are missing in order to configure
EFI variables and the efibootmgr though. Since U-Boot's default config
enables other EFI related commands (e.g bootefi), let's add the env related
and efidebug commands and allow users to do that

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)
3/ U-Boot executes the stm32prog command (DFU or uart)
