ish/ish5: remove watchdog disable during D0ix
ECOS will reload watchdog in hook task for every HOOK_TICK_INTERVAL
time, and this will make HPET timer 1 wakeup ish. Therefore, we do not
need to disable watchdog during D0ix.
D3 and reset prep flow still need disable watchdog.
BUG=b:132112137
BRANCH=none
TEST='waitms 10500' console command can trigger watchdog timeout and
ish reboot
