drm/tilcdc: Run DRM default client setup

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.

v5:
- select DRM_CLIENT_SELECTION
v3:
- add DRM_FBDEV_DMA_DRIVER_OPS macro
