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.
