sunxi: dts: arm64: update devicetree files from Linux-v6.6-rc6

Sync the devicetree files from the official Linux kernel tree, v6.6-rc6.
This is covering Allwinner SoCs with 64-bit ARM cores.

Only small cosmetic changes (clock name fixed), but we add the DT for
the new OrangePi Zero 3 board, for which U-Boot enablement patches are
pending.

As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.
