sunxi: dts: arm: update devicetree files

Update the devicetree files from the Linux kernel, version v6.0-rc4.
This is covering the 32-bit SoCs, from arch/arm/boot/dts/.

This avoids the not backwards-compatible r_intc binding change, to allow
older kernels to boot, but the other nodes are updated.

Not much change here, the vast majority is actually cosmetic: node names
and using symbolic names for the the RTC clocks.
The R40 boards gain DVFS support.
Some A23/A33 tablet DTs are unified into a single file.
