samus: change hibernate delay to 7 days
Add macro for default hibernate delay, and set to 7 days on samus.
Also, adds CONFIG_ option for hibernating early if low on battery.
For samus, setting early hibernate at 1 day when battery < 10%.
BUG=chrome-os-partner:33088
BRANCH=samus
TEST=make buildall
Added ccprintf("Target shutdown: %.6ld\n", target_time); to print
out target shutdown time after setting it. Verifed the following
on samus
1) If CONFIG_HIBERNATE_DELAY_SEC is left at default 3600 (samus
board.h does not overwrite it), then target time is 3600s.
2) If CONFIG_HIBERNATE_DELAY_SEC is defined in samus/board.h, then
target time equals that value.
3) If CONFIG_HIBERNATE_DELAY_SEC is defined as 1 week and
CONFIG_HIBERNATE_BATT_PCT is defined to 10% and
CONFIG_HIBERNATE_BATT_SEC is 1 day, then when battery is between 8-10%
target time is 1 day and if battery is at 11%, target time is 1 week.
