It wouldn't be appropriate for io_apic.c as it isn't generic to I/O
APICs but is specific to ACPI.  However, mptable.c is really not a
great name for this file in sys/x86/xen.  I wonder if it should be
xen_apic.c instead?  Also, if Xen PV has an MADT table, why do you
need a custom APIC enumerator at all?  That is, what is preventing
the code in madt.c from just working?  Do you just not have
'device acpi' in the kernel config you are using?
