PM: don't skip device PM init when CONFIG_PM_SLEEP isn't set and CONFIG_PM is set
This patch (as1124) fixes a couple of bugs in the PM core. The new dev->power.status field should be initialized regardless of whether CONFIG_PM_SLEEP is enabled, and similarly dpm_sysfs_add() should be called whenever CONFIG_PM is enabled. The patch separates out the call to dpm_sysfs_add() from the call to device_pm_add(). As a result device_pm_add() can no longer return an error, so its return type is changed to void.
