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.
