Subject: drm/bridge/synopsys: dsi :remove is_panel_bridge
Git-commit: d5532f65e0465af2361c8beefe6ed396025316a3

References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

When using drm_of_panel_bridge_remove() we can simplify the
code and remove is_panel_bridge from dw_mipi_dsi structure.
