[U-Boot] [PATCH v3 2/2] fit: Support compat string property in configuration node

> Can you please add a change log, as this is a v3 patch.

I didn't change anything in this one. (Should I have not called it v3
then? Sorry, I'm not familiar with the submission process here. I
thought letting the individual patches in the series have different
version numbers for the same set would be more confusing.)
