Patrick Delaunay 187c41d783 stm32mp1: ram: add tuning in DDR interactive mode 
Add command tuning for DDR interactive mode, used during
board bring-up or with CubeMX DDR tools to execute software
tuning for the DDR configuration:
- software read DQS Gating (replace the built-in one)
- Bit de-skew
- Eye Training or DQS training
