And while at it, why not finally add the DT register definitions for Allwinner A20 NFC. I'm certainly not the author of these, and they have been around for many years already. Its quite unlikely they will suddenly change, or vary between different A20-based devices. The A20 SoC is gradually becoming obsolete, so why wait any more. Note: one whould typically need to also add NFC node definition on top of this in order to actually use it.

allwinner,{pins,function,drive,pull} syntax has been deprecated in favor or general pinctrl syntax.
You can check how sun5i.dtsi defines these blocks.
