What Peter C. probably meant here was it is a pre-qdev init function.

Unless there is a strong need for reuse, just inline it into the machine
init function to show that it is using pure QOM constructs.

As for new-style init functions, since you are not setting any
properties, chances are good that you can do in an instance_init
function (rather than realize function) what you did in a deprecated
SysBus init function IIRC.
