tcpm: switch check for role_sw device with fw_node

commit 2d8713f8 upstream.

When there is no port entry in the tcpci entry itself, the driver will
trigger an error message "OF: graph: no port node found in /...../typec" .

It is documented that the dts node should contain an connector entry
with ports and several port pointing to devices with usb-role-switch
property set. Only when those connector entry is missing, it should
check for port entries in the main node.

We switch the search order for looking after ports, which will avoid the
failure message while there are explicit connector entries.
