From: Kieran Bingham <kieran.bingham@xxxxxxxxxxxxxxxx>
Provide a test to verify the hardware is functional both before and
after entering a suspend / resume cycle. Make use of the
/sys/power/pm_test functionality provided by CONFIG_PM_DEBUG to perform
the testing

v2:
- extended pipeline test to run twice to verify stop->start process
- added return value checking to track test progress
- modified test reporting to be once per 'suspend mode'
- removed trailing ';' uses
- verify the pm_test mode is available, or skip
