sunxi: dts: arm: 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 32-bit ARM cores, minus the T113s
board and related .dtsi files, which come separately.

Only small changes: Bluetooth got enabled on the C.H.I.P., and a clock
got renamed. More interesting is the addition of a 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.
