Some other drivers may be waiting for our extcon to show-up (exiting their
probe methods with -EPROBE_DEFER until we show up).
These drivers will typically get the cable state directly after getting
the extcon, this commit changes the int3496 code to process the id-pin
before registering the extcon, so that other drivers see the correct state
right away.
Fixes: 2f556bdb9f2e ("extcon: int3496: Add Intel INT3496 ACPI ... driver")
