t may not be realised with the current
design).

It's just matter of time when we face the issue in full and some poor guy will
have to address that somehow.

What I think of is having a reference to parent and child without limitations
of the length of the lists and keeping secondary as a sibling pointer.

This hierarchy will allow to have a tree of fwnodes where one may be present
in different lists as a parent and/or sibling. With that we probably may have
a tree-like structure with many possible combinations and relationships.

TL;DR: It is not a problem in MFD, it's problem in fwnode current design.
FIXME is just to make sure we won't forget this.
