google/gru: Re-enable 3V rail GPIO on Scarlet
We've decided to move control for the 3.0V rail (technically 3.3V on
Scarlet, but who cares about millivolts) back to a GPIO on the AP for
Scarlet rev2. This patch adds the necessary code to enable it and make
ARM TF aware of its existence. Since the pin had previously not been
connected to anything, we shouldn't really need to guard this by board
ID... older Scarlets will just be twiddling an empty pin.
