refactor(st-ddr): reorganize generic and specific elements
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.
