Fix the OF node pointer passed to the of_drm_find_bridge() call to find
the next bridge in the display chain.
To find the next bridge in the pipeline, we need to pass "np" - the OF
node pointer of the next entity in the devicetree chain. Passing
"of_node" to of_drm_find_bridge will make the function try to fetch the
bridge for the cdns-dsi which is not what's required.
Fix that.
