USB: serial: spcp8x5: drop broken carrier detect support

Browse source

The driver does not support modem status notifications and instead used
to fetch the modem status once at open() and subsequently operate on and
report stale state.

As part of fixing this, a call to fetch the status was added to
carrier_raised(), which does not work as that callback must not sleep
(e.g. unlike tiocmget()).

Drop the broken carrier detect support.
