extcon: int3496: Ignore incorrect IoRestriction for ID pin 

The commit

  70216fd937 ("extcon: int3496: Set the id pin to direction-input if necessary")

introduced a workaround for incorrect IoRestriction mode in ACPI table.

Now, when GPIO ACPI library does it in generic way, see the commit

  1b2ca32ab0 ("gpiolib: acpi: Introduce NO_RESTRICTION quirk")

for the details, just set an appropriate quirk flag instead.
