If a legacy vuart base is configured as "CONFIG_COM_BASE", allocate a
base with unused io-port address with length 0x10.
The post-launched VM's unused io-port address range is [0xD00, 0xFFFF].
The pre-launched VM's unused io-port address range is [0xD00, 0xFFFF]
but the passthrough devices' io-port address are reserved.
The SOS VM's unused io-port address range is [0xD00, 0xFFFF] but any
native devices' io-port address are reserved. However, the io-port
address which is passed through to any pre-launched is reusable.

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].

This file allocates the resource of pio base.
The available pio base is in ['0x3F8', '0x2F8', '0x3E8', '0x2E8'] and it
cannot be used by native device.
When any of sos legacy vuarts are enabled, assign a pio base to legancy
vuarts' base.
The allocator follows rules:
1. An SOS legacy vuart only support PIO vuart.
2. To assign a pio base for sos legacy vuart 0:
- If the hv/DEBUG_OPTIONS/SERIAL_CONSOLE is one of
[ttys0, ttys1, ttys2, ttys3] and it's a pio vuart in the native
environment, the pio base of SOS legacy vuart 0 would be the same as
native one.
- If the hv/DEBUG_OPTIONS/SERIAL_CONSOLE is not one of
[ttys0, ttys1, ttys2, ttys3], assigns a pio base to SOS legacy vuart 0
from avilable pio base.
- If the hv/DEBUG_OPTIONS/SERIAL_CONSOLE is not one of
[ttys0, ttys1, ttys2, ttys3] but a pio vuart, will assigns a pio
base to SOS legacy vuart 0 from avilable pio base and raise a
warning to user.
3. To assign a pio base for sos legacy vuart 1:
- Assigns a pio base to SOS legacy vuart 1 from avilable pio base.
- If all the available pio bases list is empty (which means all are
in used by native), it assigns one of the pio base to SOS legacy
vuart 1 anyway, but raise a warning to user.
4. Assigned pio bases must be unique.
