google/kukui: Configure AP_IN_SLEEP_L correctly
This pin should be set to its alternative function SRCLKENA0 instead of
GPIO, so that SPM (a power management component of MT8183) can control
it.
BUG=b:113367227
BRANCH=none
TEST=1. Boot. Run 'powerinfo' in EC console and see power state in S0.
2. Run 'powerd_dbus_suspend --wakeup_timeout=10', and then
run 'powerinfo' in EC console and see power state in S3.
3. Wait until AP resume.
4. Run 'powerinfo' in EC console and see power state back to S0.
