ARM: dts: stm32: Add support for environment in eMMC on STM32MP13xx DHCOR SoM

Browse source 
Enable support for environment in eMMC on STM32MP13xx DHCOR SoM,
in addition to existing support for environment in SPI NOR. The
environment size is the same, except in case the environment is
placed in eMMC, it is stored at the end of eMMC BOOT partitions
in the last 32 sectors of each eMMC HW BOOT partition.
