sunxi: DT: A64: Update devicetree files from Linux 5.12

Import updated devicetree files from the Linux v5.12 release.

Besides some node and audio port renames this changes the PHY modes to
either rgmii-id or rgmii-txid. From the board files the Pinephone sees
a lot of updates.

This also adds the long missing USB PHY property for controller 0, which
allows the U-Boot PHY driver to eventually use port 0 in host mode
(pending another U-Boot patch).
