intel-iommu: set compatibility format interrupt

When extended interrupt mode (x2apic mode) is not supported in a
system, it must set compatibility format interrupt to bypass
interrupt remapping, otherwise compatibility format interrupts
will be blocked.

This will be used when interrupt remapping is enabled while x2apic
is not supported.
