Patches 3, 4, 5, 6 applied on stm32-dt-for-v4.13

Patch 7 applied on stm32-defconfig-for-v4.13

Patch 8 will not be applied: As SDRAM used on STM32 MCUs is small,
I don't want to penalize other users:
 - by increasing static kernel size
 - by enabling devices which consume dynamically lot of memory

User will be free to enable it through menuconfig.
