arm64: dts: allwinner: h616: add NAND controller
The H616 has a NAND controller quite similar to the A10/A23 ones, but
with some register differences, more clocks (for ECC and MBUS), more ECC
strengths, so this requires a new compatible string.
Add the NAND controller node and pins in the device tree.
