There were some legacy logic of the current code, the PCI vUART index in the launch script have not count the vUART of S5 and life_mngr_win use the COM2 as default vUART. This patch change the vUART index and irq to adapt above logic and all of these legacy code will be refine next version. Tracked-On: #6690 Signed-off-by: Chenli Wei <chenli.wei@intel.com>
