better and clear name.

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.

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.

"S5" is one of the ACPI sleep states which means the function to shut
down the VMs.
On ACRN, the User VM must be shut down before powering off the Service
VM, so we need a vUART channel to communicate between the Service VM
and User VMs.
This patch adds a vUART channel for each User VM connect to Service VM
