This patchset introduces a basic support for Digital Camera Memory Interface
(DCMI) of STMicroelectronics STM32 SoC series.
This first basic support implements RGB565 & YUV frame grabbing.
Cropping and JPEG support will be added later on.
This has been tested on STM324x9I-EVAL evaluation board embedding
an OV2640 camera sensor.

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.

Alex
