usb: typec: ps883x: Fix Oops at unbind

When trying to unbind a device in order to bind to it vfio-platform as:

echo bc0000.geniqup > /sys/bus/platform/devices/bc0000.geniqup/driver/unbind

I get the following Oops:

That's because the ps883x_retimer_remove() retrieves the driver data from i2c_get_clientdata() which was never set at probe. So, add i2c_set_clientdata() at the end of the probe.
