[PATCH v1 1/4] PM / wakeup: Add dev_wakeup_path() helper

[patrice.chotard]

From: Patrice Chotard <patrice.chotard@xxxxxx>

Add dev_wakeup_path() helper to avoid to spread
dev->power.wakeup_path test in drivers.

In case CONFIG_PM_SLEEP is not set, wakeup_path is not defined,
dev_wakeup_path() is returning false.
