Modify the DDR driver to handle the DDR power supplies when a PMIC is present in the function stm32mp_board_ddr_power_init(), define in the platform file. This patch allows to easily modify the used DDR power supplies for customer boards, when they don't use STPMIC1 PMU or when the regulators are not connected as on the STMicroelectronics boards.
