I could see wanting to use the same string in the driver for a small
size savings, but I'd assume a mainline driver would do away with the
firmware text file and only use DT? Also, do you expect lots more
properties? Maintaining the exact string would be more worthwhile if
there are lots of properties.

I plan to make '_' cause warnings with dtc which is why we don't want
to add more.
