google/storm: use whirlwind LED ring on SP5 boards 

The latest whirlwind requirements call for the need to indicate
different device states while it is still in coreboot (it could be
waiting for recovery or for factory reset trigger).

Initialize the LED ring when running on the SP5 hardware (which is the
first proper Whirlwind device).

BRANCH=storm
BUG=chrome-os-partner:36059
TEST=when the device starts the LED ring gets shut down
