misc: modify the vUART index order and irq

Browse Source 
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.
