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").
