kevin: Add Sensor in S3, disable keyboard wakeup in tablet mode.

Browse Source 
Let sensor be powered on in S3. It is useful for Android and if we want to
disable keyboard wakeup based on lid angle.
Allow EC to disable touchpad and not send keyboard events when lid angle
is greater than 180.

BUG=chrome-os-partner:57510,chromium:620633
BRANCH=gru
TEST=In S3, check the sensors are readable.
Check that when in S3 and lid angle is < 180 EC sends keyboard events.
Check that when in S3 and lid angle is > 180 EC does not send keyboard
events.
