Eventually maybe, but not for the initial change.

It is complicated, making this change has side-effects
and we want to limit those side-effects to only i2c-clients
instantiated from serial-multi-instantiate for now, see
my other reply to this patch.

I do believe that we eventually want to make this change,
to easily give drivers access to all sorts of info
(e.g. _DSM methods) from the matching ACPI fw-node,
but as I said it is complicated...
