Expand the capacity of legacy vuarts per VM. This change is applied to
manual scenario xml editing only.
A SOS VM can choose io port 0x3F8, 0x2F8, 0x3E8, 0x2E8 by selecting
SOS_COM1_BASE, SOS_COM2_BASE, SOS_COM3_BASE, SOS_COM4_BASE respectively.
Non SOS VM can choose io port 0x3F8, 0x2F8, 0x3E8, 0x2E8 by selecting
COM1_BASE, COM2_BASE, COM3_BASE, COM4_BASE respectively.
For any type of VM, selecting "CONFIG_COM_BASE" allows configuration tool
to pick an available io port from hardcoded list:
['0xA000', '0xA010', '0xA020', '0xA030', '0xA040', '0xA050', '0xA060', '0xA070']
A SOS VM can choose irq 4 by selecting SOS_COM1_IRQ and SOS_COM3_IRQ, and choose irq 3 by selecting SOS_COM2_IRQ and SOS_COM4_IRQ.
Non SOS VM can choose irq 4 by selecting COM1_IRQ and COM3_IRQ, and choose irq 3 by selecting COM2_IRQ and COM4_IRQ.
For SOS VM, selecting "CONFIG_COM_IRQ" allows configuration tool
to pick an available irq based on AVAILABLE_IRQ_INFO. For non SOS VM, it
will allocate an available irq from [1, 15].
