usb: typec: Set the bus also for the port and plug altmodes

The port and plug altmodes can't be bound to the altmode
drivers because the altmode drivers are meant for partner
communication using the VDM (vendor defined messages), but
they can still be part of the bus. The bus will make sure
that the normal bus notifications are available also with
the port altmodes.

The previously used common device type for all alternate
modes is replaced with separate dedicated device types for
port, plug, and partner alternate modes.
