ARM: dts: stm32: Add 1 GiB DRAM settings for DH STM32MP13xx DHCOR SoM
Add DRAM settings for 1 GiB variant of DH STM32MP13xx DHCOR SoM
and support for SoM DRAM coding HW straps decoding and automatic
DRAM configuration selection. Enable CONFIG_BOARD_EARLY_INIT_F on
all STM32MP1 DHSOM, as it is required for the HW straps decoding.
