Subject: [PATCH 2/2] power: sysfs: move wakeup related nodes in power dir to obselete.
As we have a new wakeup_source sub directory under power/ that
exposes all the wakeup_source related attributes, move the
documentation pointing to the existing attributes directly
under power/ directory to obselete.
