Appended, on top of your patch.  It only moves the code around and adds
#ifdefs.

Subject: Net / e1000e: Fix build issue introduced by runtime PM patch

The recent PCI runtime PM patch broke build for CONFIG_PM_RUNTIME
and CONFIG_PM_SLEEP undefined.  Fix that by moving the PM callbacks
under suitable #ifdefs.
