OF graph endpoint connections must be bidirectional. Fix 2 missing
connections to the STM output port:
arch/arm64/boot/dts/arm/juno-r1.dtb: Warning (graph_endpoint): /stm@20100000/port/endpoint: graph connection to node '/funnel@20130000/ports/port@1/endpoint' is not bidirectional
arch/arm64/boot/dts/arm/juno-r2.dtb: Warning (graph_endpoint): /stm@20100000/port/endpoint: graph connection to node '/funnel@20130000/ports/port@1/endpoint' is not bidirectional
