of: Explicitly include linux/types.h in of_graph.h

In current -next of_graph.h fails to build due to it relying on
linux/types.h without explicitly including it:

../include/linux/of_graph.h:43:71: error: unknown type name 'u32'

caused by bfe446e37c4e (of: Add of_graph_get_port_by_id function).  Add
an explicit inclusion to fix this.
