Supermicro H8QGI: Fix routing from 16 to 55 in ACPI table 

H8QGI board has 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

has IO-APIC interrupt mapping for HT and IOMMU set to last 31
IRQ pin (24+31=55).

    CONST APIC_DEVICE_INFO gDefaultApicDeviceInfoTable[] = {
    // Group  Swizzling   Port Int Pin
      {0,     0,          31},   //HT
      {0,     0,          31},   //IOMMU
    […]

Also the same value (55) can be found in original Supermicro BIOS ACPI DSDT.
