/*
* Power Tree
*
* In general an attempt is made to include all rails called out by
* the schematic as long as those rails interact in some way with
* the AP. AKA:
* - Rails that only connect to the EC (or devices that the EC talks to)
* are not included.
* - Rails _are_ included if the rails go to the AP even if the AP
* doesn't currently care about them / they are always on. The idea
* here is that it makes it easier to map to the schematic or extend
* later.
*
* If two rails are substantially the same from the AP's point of
* view, though, we won't create a full fixed regulator. We'll just
* put the child rail as an alias of the parent rail. Sometimes rails
* look the same to the AP because one of these is true:
* - The EC controls the enable and the EC always enables a rail as
* long as the AP is running.
* - The rails are actually connected to each other by a jumper and
* the distinction is just there to add clarity/flexibility to the
* schematic.
