drm/atmel-hdlcd: Run DRM default client setup

Call drm_client_setup_with_fourcc() to run the kernel's default client
setup for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

v5:
- select DRM_CLIENT_SELECTION
v3:
- add DRM_FBDEV_DMA_DRIVER_OPS macro (Sam)
v2:
- use drm_client_setup_with_fourcc()
