As per HID over I2C Protocol Specification[1] Version 1.00 Section 7.4,
the interrupt line used by the device is required to be level triggered.
Hence, this change updates the configuration of the HID over I2C devices
to be level triggered.

LTE module Fibocom L850-GL is lost after idle overnight, with this workaround, host will not initiate U3 wakeup at the same time with device, which will avoid the race condition.
