drm/sun4i: backend: Add a custom atomic_check for the frontend 
Now that we have everything in place, we can start enabling the frontend.
This is more difficult than one would assume since there can only be one
plane using the frontend per-backend.

We therefore need to make sure that the userspace will not try to setup
multiple planes using it, since that would be impossible. In order to
prevent that, we can create an atomic_check callback that will check that
only one plane will effectively make use of the frontend in a given
configuration, and will toggle the switch in that plane state so that the
proper setup function can do their role.
