[PATCH] PM / wakeup: Register class wakeup in pure_initcall phase

[Heiner Kallweit <hkallweit1@gmail.com>]

Wakeup sources (e.g. autosleep) can be created as early as core_initcall.
Class wakeup is registered in postcore_initcall only, what results in
autosleep wakeup source not being shown in sysfs. To fix this,
register class wakeup in pure_initcall phase already.

The current behavior doesn't cause any known issue, therefore treat
the change as an improvement.
