Mark old list-based power managment as deprecated

Mark old list-based power managment as deprecated

[Pavel Machek]

Hi!

This should prevent people from using pm_requests (etc) in new
code. If we have to create typedefs, we may as well use enums in
them. This is against -rc3, I'm not sure if pm_find was not killed
already in -mm.
