The legacy code get all non-stand vUARTs from scenario_etree and generate the serial.conf, now we need add more non-stand vUARTs which was config by offline tool and record by allocation_etree. This patch add allocation_etree to the list, then add all non-stand vUART to serial.conf which will config by SERVICE VM. Tracked-On: #6690 Signed-off-by: Chenli Wei <chenli.wei@intel.com>
