2be64048c1 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.

Do not assert GPIO1_B3 otherwise BT would be disabled on Nefario.
Also, remove DVS support for CENTERLOGIC.

6486e7819c google/gru: Add support for Scarlet rev1
This patch adds the necessary changes to support Scarlet revision 1.
Since the differences to revision 0 are so deep, we have decided not to
continue support for it in the same image. Therefore, this patch will
break Scarlet rev0.

All the deviations from other Gru boards are currently guarded by
CONFIG_BOARD_GOOGLE_SCARLET. This should be changed later if we
introduce more variants based on the newer Scarlet board design.

7d8ccfb9b3 google/gru: pass the gpio power supply enable pin to bl31
We need to disable some regulators when the device goes into suspend.
This means that we need to pass some gpios to bl31, and disable these
gpios when bl31 runs the suspend function.

BRANCH=None
BUG=chrome-os-partner:56423
TEST=enter suspend, measure suspend gpio go to low

[pg: also update arm-trusted-firmware to match]
