Song Gao dc6f37eb95 hw/intc/loongarch_extioi: Add extioi virt extension definition 
On LoongArch, IRQs can be routed to four vcpus with hardware extended
IRQ model. This patch adds the virt extension definition so that
the IRQ can route to 256 vcpus.

    1.Extended IRQ model:
                                    |
    +-----------+     +-------------|--------+     +-----------+
    | IPI/Timer | --> | CPUINTC(0-3)|(4-255) | <-- | IPI/Timer |
    +-----------+     +-------------|--------+     +-----------+
                            ^       |
                            |
                       +---------+
                       | EIOINTC |
                       +---------+
                        ^       ^
                        |       |
                 +---------+ +---------+
                 | PCH-PIC | | PCH-MSI |
                 +---------+ +---------+
                   ^      ^          ^
                   |      |          |
            +--------+ +---------+ +---------+
            | UARTs  | | Devices | | Devices |
            +--------+ +---------+ +---------+

    2.Virt extended IRQ model:

      +-----+    +---------------+     +-------+
      | IPI |--> | CPUINTC(0-255)| <-- | Timer |
      +-----+    +---------------+     +-------+
                        ^
                        |
                  +-----------+
