    Supermicro H8QGI: fix routing in acpi table
    
    H8QGI board have 2 IO-APICS with 56 irq's:
    
    IOAPIC[0]: GSI 0-23    - SB700 southbridge
    IOAPIC[1]: GSI 24-55   - RD890 northbridge
    
    "gDefaultApicDeviceInfoTable[]" structure in northbridge code
    vendorcode/amd/cimx/rd890/nbIoApic.c
    have IO APIC interrupt mapping for HT and IOMMU to last 31 irq pin (24+31=55)
    
    Also the same value (55) can be found in original supermicro BIOS ACPI DSDT table.
