Subject: PM / Hibernate: Remove deprecated hibernation test modes

The hibernation test modes 'test' and 'testproc' are deprecated, because
the 'pm_test' framework offers much more fine-grained control for debugging
suspend and hibernation related problems.

So, remove the deprecated 'test' and 'testproc' hibernation test modes.
