Waddledee: Enable MB USB-A Vbus
As of board revision 1, there is a GPIO to enable Vbus for the type-A
port. Turn this GPIO on when we're booted, and off when the system is
shut down. This pin is NC on revision 0, so it should be fine to set
regardless of hardware version.
BRANCH=None
BUG=b:160336151
TEST=on waddledee rev 1, able to use flash drive plugged into MB
