[PATCH v4 42/80] drm/tilcdc: Run DRM default client setup

[Thomas Zimmermann]

Call drm_client_setup_with_color_mode() 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.

v3:
- add DRM_FBDEV_DMA_DRIVER_OPS macro

tilcdc patch looks identical to the previous version, but here is my ack again:
