ARM: dts: stm32mp15: update DDR node

Browse source 
Remove the unnecessary nodes for TFABOOT and keep the mandatory part
in SOC dtsi, only the DDRCTRL and DDRPHY addresses.
This patch allows to manage the DDR configuration setting in U-Boot
device tree only if it is needed, when CONFIG_SPL is defined.

With TFABOOT, the DDR configuration is done in TF-A BL2 and the DDR size
is dynamically computed in U-Boot since commit d72e7bbe7c ("ram:
stm32mp1: compute DDR size from DDRCTL registers").
