bnxt: Move GENEVE support from hard-coded port to using port notifier

Orabug: 24567991

The port number for GENEVE is hard coded into the bnxt driver.  This is the
kind of thing we want to avoid going forward.  For now I will integrate
this back into the port notifier so that we can change the GENEVE port
number if we need to in the future.
