Quite a bit of stuff in a single commit, this could be
separated into:

- scm icc
- aoss+ipcc
- smp2p+mpss

Not sure if thunderfox is acting up again or the indentation here
is not quite right

The address part should be padded to 8 hex digits. I'd appreciate it
if you could submit a fixup for the other nodes in this dtsi!

No reg-names?

This could be a vertical list, similar to the interrupts-extended itself

cx
ebi
mx

would be alphabetical, unless there's some strong ordering required,
not sure
