[PATCH 3/3] ipuv3-ldb: add remove action for devres data

. This leads drm_encoder_cleanup try to clean already freed memory. We fix this issue by adding the devres action ipu_ldb_remove_head which will remove its head from the objects in ipu-drm-core which then never calls its destroy function anymore.
