[PATCH] extcon: int3496: process id-pin first so that we start with the right status

[Hans de Goede <hdegoede@redhat.com>]

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.
