supermicro/h8qgi/dsdt: Use PIC as default interrupt model

According ACPI specification:

"""
    The _PIC optional method is used to report to the BIOS the current
    interrupt model used by the OS. The argument passed into the method
    signifies the interrupt model OSPM has chosen, PIC mode, APIC mode,
    or SAPIC mode. Notice that calling this method is optional for OSPM.
    If the method is never called, the BIOS must assume PIC mode.

Arguments: (1)
    Arg0 – An Integer containing a code for the current interrupt model:
    0 –PIC mode
    1 –APIC mode
    2 –SAPIC mode
    """

In current configuration with default value of interrupt model
    PMOD equal 1 (APIC mode), Linux can't boot with "noapic" option.
    Kernel never call _PIC method and PMOD stays equal 1, indicatind
    that APIC routing objects should be evaluated. This mix of PIC
    and APIC leads to boot fail.

Change default value of interrupt model PMOD to 0, for correct
    "noapic" boot.
