Samuel Holland 2c597855aa ARM: dts: sunxi: H2+/H3/H5: Sync from Linux v5.18-rc1
Copy the devicetree source for the H2+/H3/H5 SoCs 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 994e5818392c and 9fdef3c3d8c2.

This commit also adds the following new board devicetree:
 - sun8i-h3-nanopi-r1.dts

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