soc/intel/apollolake: add offset of GPIO_TIER1_SCI_EN bit 

This patch adds the support for gpio_tier1_sci_en bit which
needs to be set before going to sleep so that when
gpio_tier1_sci_sts bit gets set platform can wake
from S3.

BUG = chrome-os-partner:53992
TEST = Platform wakes from S3 on lidopen,key press.
       Tested on Amenia and Reef boards.
