On RISC-V side I introduced the common bootfdt but probably it should
be aligned with the latest version ( my plan was to do that before
sending a patch to upstream ) of ARM's bootfdt.c.

https://gitlab.com/xen-project/people/olkur/xen/-/commit/ad2c8766a7d0886df84f6c60823275816c2115f5

I can re-work it this week and send it to the ML but I'll be happy if
Shawn can do it or his version as common so I'll be able to reuse it
soon.
