The thing I don't understand here is why would anyone want power

If we are to implement things into drivers, then callback functions
are going to serve us just as well - even better, for they are more
flexible. All we need to do is define a dedicated ops structure and
have the driver plug the right callback functions depending on the
"compatible" property of the DT device node. We don't need a framework
for that.

It allows drivers (both board drivers and actual drivers) to write these
things in a semi-scripted form instead of having to open code everything
each time, it'd save a bunch of tedious stuff with resource requesting
for example.
