If a legacy vuart base is configured as "CONFIG_COM_BASE", allocate a base with unused io-port address with length 0x10. The post-launched VM's unused io-port address range is [0xD00, 0xFFFF]. The pre-launched VM's unused io-port address range is [0xD00, 0xFFFF] but the passthrough devices' io-port address are reserved. The SOS VM's unused io-port address range is [0xD00, 0xFFFF] but any native devices' io-port address are reserved. However, the io-port address which is passed through to any pre-launched is reusable. Tracked-On: #6652 Signed-off-by: Yang,Yu-chu <yu-chu.yang@intel.com>
