> Switch the Intel networking drivers to use the new power management ops
> declaration formats and macros, which allows us to drop __maybe_unused,
> as well as a bunch of ifdef checking CONFIG_PM.

> This is safe to do because the compiler drops the unused functions,
> verified by checking for any of the power management function symbols

> If a driver has runtime PM, define the ops with pm_ptr(), and if the
> driver has Simple PM, use pm_sleep_ptr(), as well as the new versions of
> the macros for declaring the members of the pm_ops structs.

> Checked with network-enabled allnoconfig, allyesconfig, allmodconfig on
