Add support for booting from USB pen drive, since USB host
port is available on the STM32MP2.

Add support of UBI boot and activate the needed
configuration for U-Boot environment in UBI volume for
NAND or in a MTD partition for NOR device, SPI Flash:
ENV_OFFSET, ENV_OFFSET_REDUND, ENV_SECT_SIZE is
aligned with the default MTD partition on NOR device
of the STMicroelectronics boards.

Handle boot for the 3 instance of MMC and call the command stm32prog
for serial boot on USB or on UART as it is done for other STM32MP platform.

Add initial support for STM32MP2 SoCs family.
SoCs information are available here :
https://www.st.com/content/st_com/en/campaigns/microprocessor-stm32mp2.html
Migrate all MP1 related code into stm32mp1/ directory
Create stm32mp2 directory dedicated for STM32MP2 SoCs.
Common code to MP1, MP13 and MP25 is kept into
arch/arm/mach-stm32/mach-stm32mp directory :
- boot_params.c
- bsec
- cmd_stm32key
- cmd_stm32prog
- dram_init.c
- syscon.c
- ecdsa_romapi.c
For STM32MP2, it also :
- adds memory region description needed for ARMv8 MMU.
- enables early data cache before relocation.
During the transition before/after relocation, the MMU, initially setup
at the beginning of DDR, must be setup again at a correct address after
relocation. This is done in enables_caches() by disabling cache, force
arch.tlb_fillptr to NULL which will force the MMU to be setup again but
with a new value for gd->arch.tlb_addr. gd->arch.tlb_addr has been
updated after relocation in arm_reserve_mmu().
