acrn-config: chose ttyS1 for vuart1

Browse Source 
For vuart1, if it's mapped to a real native serial port, we must
re-use the native serial port io base and irq number. If no native
serial port is mapped to vuart1, non-exist io base and irq should
be used.

Please note: UOS launch script may need be updated according to
which serial port index is used by vuart1.

Now, we are using ttyS1 of SOS for vuart1 in our release. User may
need to remap vuart to different ttySx by following above rule if
ttyS1 in user platform is used by other devices like Bluetooth/Wifi.
