That's a binding for a property on the /chosen node, that as the text
says it's defined for arm64 only and the code that handled it was also
on arm64. Instead the reserved-region binding I used is a standard
binding, if you don't like the name used for the compatible string
because it overlaps with that property we can change it. I want to use a
reserved-region for this because we'll have to reserve it anyway so
using a property on /chosen and then using that property to reserve the
region seemed suboptimal.

No special handling is needed when using linux,usable-memory on /memory,
limiting the available memory is handled by generic code at
