Probably simpler to reply here, rather than to the patches themselves.

First I'd heard that this is now the defacto format.  That certainly
wasn't the case when these patches were first authored.  I will adopt
it from now on.

These were left out due to historical reasons, but yes, they should be
in there now.  Will change.

Depends what your reasons are for not wanting it in DT.  The node has
no real use, dispite testing, so I can't really justify it being in
the upstream kernel.  Will remove.

Not sure what you mean here.  Again, there have been some changes over
time.  The evolution of change is reflected in the two RemoteProc
patches in the set.  The resultant file should conform to the
documented bindings.
