Sync the devicetree files from the official Linux kernel tree, v6.4-rc2. This is covering both 64-bit and 32-bit Allwinner SoCs with Arm Ltd. cores, we skip the new RISC-V bits for now, as sunxi RISC-V support is still work in progress.

Among smaller cosmetic changes, this adds a SATA regulator node which we need in U-Boot to get rid of hard-coded GPIOs. Also this updates the Allwinner F1C100s DTs, enabling USB support, and also adds the DTs for two new boards.

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