drm/sun4i: backend: Allow a NULL plane pointer to retrieve the format
The function converting the DRM format to its equivalent in the backend
registers was assuming that we were having a plane.
However, we might want to use that function when setting up a plane using
the frontend, in which case we will not have a plane associated to the
backend's layer. Yet, we still need to setup the format to the one output
by the frontend.
Test for NULL plane pointers before referencing them, so that we can work
around it.
