ACPI: disable MPS when NO APIC-table found
When ACPI is asked to find an MADT (APIC table)
and fails, then ACPI expects to run in PIC mode.
However, if an MP Table is was found, IRQs will be
registered as if an IOAPIC is being used, even
though ACPI is configuring interrupt links links for PIC mode.
In this scenario, disable MPS so that IRQs
are registered in PIC mode, consistent with ACPI.
