In retrospect we should've just used "reg" in the first place rather
than adding the custom "nvidia,ram-code". It's a bit redundant to have
both of them with the same value. I wonder if we should deprecate the
use of "nvidia,ram-code" and at least make the code look at the "reg"
property first and only fall back to "nvidia,ram-code" if "reg" does
not exist. We probably won't ever be able to get rid of the fallback
for backwards-compatibility reasons, but at least that would make the
intent a bit clearer.
