[PATCH RFC V2 0/4] Add "scope" to power supplies

[Jeremy Fitzhardinge <jeremy@goop.org>]

This series adds a "scope" attribute to power supplies, to indicate
whether it powers the whole system ("System") or just some subset of
the devices ("Device").  This allows upowerd to distinguish between
system-wide power supplies and self-powered devices such as cordless
mice.

This series also adds a "powers" link to power supplies, so that if
they're scope=Device, they can specifically indicate which device
tree they power.

Updates since last post:
 - Add more complete documentation to scope and "powers" links
 - Remove unnecessary scopes on System power supplies
 - Make HID battery supplies Device, and add "powers" pointers
   for them.

    device
