drm/bridge: nwl-dsi: Drop the drm_of_panel_bridge_remove() function call

Since this driver has been changed to use the resource managed
devm_drm_of_get_bridge() to get bridge from ->attach(), it's
unnecessary to call drm_of_panel_bridge_remove() to remove the
bridge from ->detach().  So, let's drop the drm_of_panel_bridge_remove()
function call.  As nwl_dsi_bridge_detach() only calls
drm_of_panel_bridge_remove(), it can also be dropped.
