sunxi: DT: A64: update device tree files

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.
