platform/chrome: cros_ec_typec: Avoid setting usb role twice during disconnect

Browse Source 
On disconnect port partner is removed and usb role is set to NONE.
But then in cros_typec_port_update() the role is set again.
Avoid this by moving usb_role_switch_set_role() to
cros_typec_configure_mux().
