Subject: [PATCH v2 2/2] usb: typec: tcpm: Remove altmode active state updates

Since the "active" state for partner altmodes is now being taken care of
by the altmode driver itself (specifically, DisplayPort altmode), we
no longer need to do so from the port driver. So remove the calls to
typec_altmode_update_active() from TCPM.
