[PATCH] drm/bridge: adv7511: Remove a redundant check on existence of bridge->encoder

In the adv7511_connector_init() function, the check on the existence
of bridge->encoder is not necessary, as it has already been done in the
drm_bridge_attach() function. And the check on the drm bridge core
happens before check in the implementation. Hence, it is guaranteed that
the .encoder member of the struct drm_bridge is not NULL when
adv7511_bridge_attach() function is called.

Remove the redundant checking codes "if (!bridge->encoder) { ... }".
