sunxi: dts: arm64: update devicetree files from Linux kernel tree

Sync the devicetree files from the official Linux kernel tree, v6.18-rc1.
This is covering Allwinner SoCs with 64-bit ARM cores.

The bulk is cosmetic changes: board model name changes, DT node renames,
whitespace fixes.
The actual changes are not dramatic: the CPU cores get their caches
described properly, some A64 video clocks get fixed, some A64 boards
describe the header pins for the WiFi module, the Pinephone adds an
alternative magnetometer used on some board revisions.
On the H5 side the microSD slots get marked as having no write-protect
detection, and the NanoPi Neo Plus2 board describes its regulators better.
The H6 boards switch from RSB to I2C for their PMIC connection.

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