[arm64] Improve support for rk3328/rk3399/rk356x devices

Analysing the various .dtsi files based on the "compatible" strings revealed that several modules were available in the built arm64 kernel, but were not (explicitly) enabled in Debian's kernel configuration. It also showed that some kernel modules were not available at all.

Make the implicit modules explicit and add the missing ones. New modules are marked with (*).
Details are in the individual commit messages.
