Cr50: I2CS: Set INT_AP_L as in input  when the AP is off

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.
