drm/debugfs: Drop conditionals around of_node pointers

Having conditional around the of_node pointer of the drm_bridge structure
is not necessary anymore, since drm_bridge structure always has the of_node
member since the commit d8dfccde ("drm/bridge: Drop conditionals around
of_node pointers").

So drop the conditional, please also note that this patch is following the
convention used by driver core, see commit c9e358df ("driver-core:
remove conditionals around devicetree pointers").
