[PATCH v2 2/3] usb: typec: fusb302: Implement start_toggling for all port-types

[Hans de Goede]

When in single-role port mode, we must start single-role toggling to
get an interrupt when a device / cable gets plugged into the port.

This commit modifies the fusb302 start_toggling implementation to
start toggling for all port-types, so that connection-detection works
on single-role ports too.

Fixes: ea3b4d5523bc("usb: typec: fusb302: Resolve fixed power role ...")

Changes in v2:
-Adjust for the tcpm core renaming start_drp_toggling to start_toggling,
 instead of adding a new start_srp_connection_detect callback
