option,hso: early check of port type hints to avoid probings
Instead of getting the port type hints while grabbing each probed port, we now run a custom init operation in the probing which already gives us the port type, and therefore allows us to completely skip port probings. Also now added hints for 'Diag' (QCDM) ports and AT/'Modem' ports (I guess it's the one for PPP if we don't have a net port, which is unlikely anyway in HSO). This makes the probing of an Option/HSO modem almost instant.
