stm32mp1: Reduce MAX_XLAT_TABLES to 4
For STM32MP1, the address space is 4GB, which can be first divided
in 4 parts of 1GB. This LVL1 table is already mapped regardless
of MAX_XLAT_TABLES.
Fixing typo: Replace Ko to KB.
BL2/sp_min for platform STM32MP1 requires 4 MMU translation tables:
- a level2 table and a level3 table for identity mapped SYSRAM
- a level2 table mapping 2MB of BootROM runtime resources
- a level2 table mapping 2MB of secure DDR (case BL32 is OP-TEE)
