drm/i2c: tda998x: Add support for atomic modesetting 

When used with a DRIVER_ATOMIC enabled CRTC driver, the tda998x
will cause crashes due to missing atomic operations. Fill the
drm_connector_funcs struct with the atomic versions of the required
functions and add the atomic modeset specific callbacks.
