Subject: [PATCH iwl-next v2 2/2] net: intel: implement modern PM ops declarations

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
being present in System.map for a build without CONFIG_PM.

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
x64_64.
