max77759_charger: Enable CHG_INT_OK.AICL_OK interrupt

CHG_INT_OK.AICL_OK tracks whether the input voltage
regulation loop is kicking in. Vote on AICL_ACTIVE_EL
when the status changes.

No evidence of system rapidly going in and out of AICL
to cause interrupt storm so far. If needed,
CHG_INT_OK.AICL_OK can be throttled. i.e. enable once
per plug-in event.

Bug: 273366006
Test: Connect to a weak power source and make sure
AICL interrupts are triggered.
