ARM: dts: sun50i: H6: Sync from Linux v5.18-rc1

Copy the devicetree source for the H6 SoC and all existing boards
from the Linux v5.18-rc1 tag.

To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 189bef235dd3 and 73088dfee635.

This commit also adds the following new board devicetrees:
 - sun50i-h6-pine-h64-model-b.dts
 - sun50i-h6-tanix-tx6-mini.dts

This update should not impact any existing U-Boot functionality.
