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().
