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.
