FWIW, this commit log is slightly misleading because .suspend and
.resume are NULL by default, so this patch actually is a complete
no-op as far as code generation is concerned.

This change is worthwhile because it simplifies the code a little, but
it doesn't convert the driver from legacy to generic power management.
This driver doesn't supply a .pm structure, so it doesn't seem to do
*any* power management.
