MLK-16727-2 Revert "MLK-16285-5 extcon: extcon-ptn5110: only sends EXTCON_USB_HOST...

This reverts 'commit cca4c561e412 ("MLK-16285-5 extcon: extcon-ptn5110:
only sends EXTCON_USB_HOST event")'

Some controllers (eg, Cadence USB3) need to know vbus disconnection
status for its internal state machine, so we need Type-C chip to
send this event as well.
