We discussed with Marek Szyprowski that either we can go back to
64-bit addressing or stick to 32. There are not known boards with more
than 4 GB of RAM so from this point of view the choice was irrelevant.
At the end of discussion I mentioned to stick with other arm64 boards
(although not all), so revert to have 64 bit address... but Marek
chosen differently. Since you ask, let's go back with revert.

Indeed, binding requires both address and size cells. I'll drop it.
