When I originally was writing this header, I abused DT_PROP()
liberally when trying to access other generated macros as a
convenience to save a bit of typing.
Somewhere during the v2.3 timeline, though, I realized that adding the
DT_CAT(), DT_CAT2(), etc macros was going to be needed in order to
recursively expand macro arguments, so we could do things like this:
#define INDEX 3
DT_FOO_BY_IDX(..., INDEX)
So I duly added those in and used them wherever something broke, but
it's been a longstanding TODO for me to clean this up and apply
recursive expansion of public DT API macro arguments consistently.
Do that now.
