Sebastian Reichel 8c0984e5a7 power: move power supply drivers to power/supply
This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
