'/memory' nodes always have a 'reg' property, and therefore should have
a unit-address with just plain hex (i.e. no commas). Fix all the arm64
'/memory' nodes.

It's possible that some bootloader depends on /memory (arm32 ATAG to DT
code does for example). If so, the memory node should be commented with
that requirement.

SoC maintainers, please take this directly.

arm32 is much worse, but the platforms using ATAG to DT code can't be 
changed and I don't know which ones those are.
