Merge tag 'sunxi-dt-for-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into soc/dt

Allwinner device tree changes for 6.19

The A523 family gains support for I2S and SPDIF audio interfaces, as
well as the GMAC200 Ethernet controller.

The H616 gains support for the NAND controller.
