I'm not sure about our collective idea of "better". I simply saw a
helper function duplicated with minor variations because it fails to
capture what's truly common, so I fixed that.
If we think helper functions capturing device creation and property
setting are bad, and open coding would be better. then we should get rid
of pflash_cfi01_register() and pflash_cfi02_register() everywhere, not
just avoid it in these three places.
Cc'ing the usual QOM suspects for guidance.
