    hw/loongarch/virt: Set MADT revision to 6

    The LoongArch virt machine emits Core PIC, EIO PIC, MSI PIC and BIO PIC
    subtables, but advertises MADT revision 1. Revision 1 predates these
    LoongArch interrupt controller structures.

    ACPI 6.5 introduced the LoongArch interrupt controller structures and
    defined MADT revision 6. ACPI 6.6 raises the MADT revision to 7 for the
    additional RISC-V interrupt controller structures, while leaving the
    LoongArch structures unchanged.

    Since the virt machine emits only the LoongArch structures defined by
    ACPI 6.5, set the MADT header revision to 6, the minimum revision that
    describes the table contents.
