In it6505_bridge_attach(), the check on the existence of bridge->encoder
has already been done in the implementation of drm_bridge_attach(). And
it is done before the bridge->funcs->attach function hook is called. Hence,
it is guaranteed that the .encoder member of the struct drm_bridge is not
NULL when the panel_bridge_attach() is called.
There is no need to check the existence of bridge->encoder another time,
remove the redundant checking codes "if (!bridge->encoder) { ... }".
