drm/bridge: anx7625: Fix refcount bug in anx7625_parse_dt() 

In anx7625_parse_dt(), 'pdata->mipi_host_node' will be assigned a
new reference with of_graph_get_remote_node() which will increase
the refcount of the object, correspondingly, we should call
of_node_put() for the old reference stored in the 'pdata->mipi_host_node'.
