Such functions are quite idiomatic in drivers, and serve to simplify all
the call-sites by removing the need to write out the addition of the
base address everywhere.

We do have basic system suspend/resume support. However, I don't think
missing suspend/resume in an individual driver should stop it from being
merged. It can certainly be added later.
