cheza: Support confirmation of power lost
Keep the timestamp of the latest power lost. Add a handler to wake
the chipset task to check if power lost stays low for a while (the
time between now and the latest power lost is longer than a period).
BRANCH=none
BUG=b:78455067
TEST=Toggle EC GPIO SYS_RST_L for a low pulse to execute PMIC reset
sequence and verified AP reset but not a transition S0 -> S5.
TEST=Toggle EC GPIO PMIC_KPD_PWR_ODL and SYS_RST_L for a low pulse
(see power_off function) to execute PMIC shutdown sequence and verified
a power-lost transition S0 -> S5.
