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 d72e7bbe7c28 ("ram: stm32mp1: compute DDR size from DDRCTL registers").
