From: Magnus Damm <damm@xxxxxxxxxx>
This is V2 of the platform driver power management late/early
callback removal patch. The callbacks ->suspend_late() and
->resume_early() are removed since all in-tree users now have
been migrated to dev_pm_ops.
Signed-off-by: Magnus Damm <damm@xxxxxxxxxx>

Untested but compiles fine.
Changes since V1:
- none, just rediff to fit upstream changes
