reef: Enable external power interrupt GPIO

Browse Source 
BUG=chrome-os-partner:54503
BRANCH=none
TEST=Manually tested using console commands on both the ports.
     a. Issued 'gpioget AC_PRESENT', observed AC_PRESENT is
        1 when AC connected & 0 when AC disconnected.
     b. Issued 'hibernate' & on plugging in the AC, device
        boots to S0.
