I thought u-boot is a pretty complete UEFI implementation now. If
there's standard way for UEFI to provide this, then that's what we
should be using. I know supporting this has been discussed in context of
EBBR spec, but no one involved in that has been CC'ed here.

/chosen node entries go in chosen.yaml schema in dtschema repository.
But first, I need to see some agreement this is how we want to support
this.
