google/kukui: Notify EC that AP is in S0
We have a pin from AP to EC, called AP_IN_SLEEP_L (SRCLKENA0 on AP side,
pad R23) that is supposed to be high in S0, and low in S3 (and X/don't
care in S5).
This should be set as early as possible in bootblock.
BUG=b:113367227
TEST=make; boots and verified AP_IN_SLEEP_L GPIO is high.
BRANCH=None
