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.
