[PATCH v11 4/9] drm/mediatek: Add encoder_index interface for mtk_ddp_comp_funcs

To support dynamic connector selection function, each ddp_comp need to get their encoder_index to identify which connector should be selected. Add encoder_index interface for mtk_ddp_comp_funcs to get the encoder identifier by drm_encoder_index(). Then drm driver will call mtk_ddp_comp_encoder_ind
