INT_AP_L is used as a sync trigger to the host during i2cs transactions. This signal is nominally set high and pulled up to 1.8V. However, when the AP is off, this line won't be pulled up which would lead to excessive power draw by the Cr50 if this signal remains driven high. Added a change to set this signal as an input while the AP is powered off. When the AP powers back up, it's changed back to an input and driven high which is the default level.
