"It was decided" that we want to power on if we are off and there is
live USB power arriving (== "insertion").  This is to solve the charging
indication while off issue, we just make ourselves "on" all the way into
X.  This will also solve the "no charging when PMU left on its own if
charger off was the last order" issue as a side effect.

What is meant to happen if you have USB power and you tell the device to
shutdown -h now I dunno.
