arm: stm32mp: correct the ALIGN macro usage

Correct the ALIGN macro usage in mmu_set_region_dcache_behaviour
call: the address must use ALIGN_DOWN and size can use ALIGN macro.

With STM32_SYSRAM_BASE=0x2FFC0000 and MMU_SECTION_SIZE=0x100000 for
STM32MP15x the computed address was 30000000 instead of 2ff00000.
