stm32mp1: ram: add tuning in DDR interactive mode (2019-05-23 11:38:11 +0200)

---------------------------------------------------------------- - Add various STM32MP1 fixes for serial, env, clk, board, i2c ...

- Add STM32MP1 DDR driver update: These update introduce the DDR interactive mode described in: https://wiki.st.com/stm32mpu/index.php/U-Boot_SPL:_DDR_interactive_mode

This mode is used by the CubeMX: DDR tuning tool. https://wiki.st.com/stm32mpu/index.php/STM32CubeMX

The DDR interactive mode is NOT activated by default because it increase the SPL size and slow down the boot time (200ms wait added).
