sunxi: dts: arm/arm64: update devicetree files from Linux-v6.9

Sync the devicetree files from the official Linux kernel tree, v6.9.
This is covering Allwinner SoCs with 32-bit and 64-bit ARM cores.

Besides some cosmectic changes, this adds S/PDIF, DMA, and thermal
support to the H616 .dtsi. Nothing that U-Boot needs for itself, but
helpful to pass on to kernels.
This also adds new devicetrees, for some LonganPi H616 board, and the
Remix Mini PC. The latter will get a defconfig next.

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