Import updated device trees from Linux tag v5.9. This picks up new hardware (PinePhone, PineTab); and it drops the U-Boot specific DTSI files for the Pinebook and the Teres-I, since the ANX6345 bridge is now supported upstream. A couple of headers needed updates for recently-added hardware support.
