I have not added them in the driver yet, so I dont think it made sense
to add them when they are not present. For basic stuff it is not
required but eventually yes, so I plan to update binding and driver at
that time

They should still be required in the binding though if the hardware has
power domains. It's not like the hardware doesn't have power domains
already or can gain that ability after the fact. The driver should deal
with it when it is ready.
