mb/google/herobrine: Transition BOARD_HEROBRINE to BOARD_HEROBRINE_REV0

Deprecating Herobrine Rev0 board.  The next board is very different
from the Rev0 board (ie: Most GPIOs have been remapped).  Deprecating
and reusing the GOOGLE_BOARD_HEROBRINE Kconfig for next board and
reslotting the old GOOGLE_BOARD_HEROBRINE source under
GOOGLE_BOARD_HEROBRINE_REV0 config.  Want to keep the code around in
case somebody needs it but we can remove this code in future after we
recall all the Rev0 devices.  Also updating the remapped GPIOs to
match those of the current herobrine board.
