extcon: int3496: Request non-exclusive access to the ID GPIO

Browse Source 
Some DSDTs are buggy and do a read from the ID pin during the ACPI
initialization, causing the pin to be marked as owned by:
"ACPI:OpRegion" and causing gpiod_get() to fail with -EBUSY.

Pass the GPIOD_FLAGS_BIT_NONEXCLUSIVE flag to the gpiod_get() call
to work around this.
