panel_bridge pointer never used anywhere except the one it

Drop it from the nwl_dsi structure.

Changes for v2:
- collect Guido r-b

Note: This is patch is part of switching of devm_drm_of_get_bridge 
serious however the child node support of devm_drm_of_get_bridge is
still under-review. So send it separatly as it not related to that
API switch.
