usb: typec: tcpm/tcpci_maxim: use device managed TCPCI port deregistration
Instead of open-coding the call to tcpci_unregister_port() in various
places, let's just register a hook using devm_add_action_or_reset() so
that it gets called automatically as and when necessary by the device
management APIs.
