Merge branch 'drm-atmel-hlcdc-devel' of https://github.com/bbrezillon/linux-at91 into drm-next

The following PR add support for 3 more atmel SoCs and for some missing
features (new input formats and PRIME support).

* 'drm-atmel-hlcdc-devel' of https://github.com/bbrezillon/linux-at91:
  drm: atmel-hlcdc: add support for sama5d4 SoCs
  drm: atmel-hlcdc: add support for at91sam9n12 SoC
  drm: atmel-hlcdc: add support for at91sam9x5 SoCs
  drm: atmel-hlcdc: add RGB565 and RGB444 output support
  drm: atmel-hlcdc: add the missing DRM_ATOMIC flag
  drm: atmel-hlcdc: add PRIME support
