stm32mp_ddrctl structure contains DDRCTRL registers definitions. stm32mp_ddr_info contains general DDR information extracted from DT. stm32mp_ddr_size moves to the generic side. stm32mp1_ddr_priv contains platform private data. stm32mp_ddr_dt_get_info() and stm32mp_ddr_dt_get_param() allow to retrieve data from DT. They are located in new generic c/h files in which stm32mp_ddr_param structure is declared. Platform makefile is updated. Adapt driver with this new classification.
