mb/google/zork: Fix FPMCU_INT_L configuration
Fingerprint interrupt (FPMCU_INT_L) is level triggered and not edge triggered. Also, we are using GEVENT for wake from fingerprint and not the GPIO IRQ wake. Thus, the irq property exposed in ACPI tables does not need to be set to indicate wake for the IRQ. This change updates GPIO table to configure the pad as level triggered and drops the wake attribute for irq_gpio in overridetree. BUG=b:165612778 BRANCH=zork TEST=Verified that fingerprint still works in S0 and to wake device from S3.
